Sorry to hijack your thread!

Maybe something more like this...

Thnaks for that, great information. I've had a quick look at cross over design but it seems like just this part of the build would take a lifetime of research so I'll leave the option for future addition. If you know of any resources that can explain it clearly I'd appreciate it. I had a tinker in in Fusion today and came up with this, an adjustable port 4 inch internal diameter (internal) which can adjust from about 40-80mm length with threaded tubes. It's quite a long print, probably take a couple of days so I might need to optimise it, but you get the gist. I might look at converting an existing 4 inch pipe with an interferance fit (can be glued once you find your sweet spot). But if I know the range of port lengths for various bass frequencies it might reduce the variables and therefore the print times/materials.

That's great thanks, I think I can work it out OK, ideally i'd reuse the amp in a separate unit so that defines the width and depth to some degree. the height would hopefully make up the remainder. I take it you remove the volume of the speaker itself? some sort of cone pi calculation which I probably missed in an 80's maths lesson I could have it cut out of ply at local timber merchants/ B&Q, I can cut the holes with a jigsaw. I'm OK with soldering electrics so long as I have a schematic to work to. I could 3D print the port, is there any benefit to having it a straight cylinder (soil pipe!) or is there something more efficient, rolled edges/ vortex like/ bends? seeing as I am handy with Fusion 360 I may as well use it. But I am really in the dark as to what it all does, so following you blindly! Any benefit to adding a tweeter like on the 12 build? I dare say this is a whole other can of worms but your advice is greatly appreciated.

Hi Following with interest, I bought a Peavey TNT 160 Which has the same Scorpion 15" speaker. I bought it as a fixer upper but it didn't need a great deal doing to it, mostly cosmetic and a new jack socket which is all sorted now. After having played it a couple of weeks the sound is really growing on me, but the the weight of the thing, it has it's own event horizon! Definitely a younger fitter persons amp. I am like yourself in that I just need something to play around the house and can be moved out of the way if necessary. All these graphs mean nothing to me though. I am fairly handy with tools so I think making a box is within my skill set, probably not a pretty one though! I'm be interested in further details the dust cover you mentioned on the speaker, I took it out briefly to check for damage but I didn't see anything that resembled 30 year old foam.

I had a similar issue on a fretless. Although I wanted the lines more pronounced rather than the dots. I tried two things which are both reveresable, water slide transfers and vinyl. The water slides worked OK but were very fragile and a bit of a bugger to apply . I've had the vinyl on for a few weeks and it seems nore robust. They are both a less than a tenner off Ebay. I had the lines but I'm sure there will be dots out there somewhere for model makers. https://www.ebay.co.uk/itm/153990019923 Edit, sorry just saw your not interested in stickers... -

That's my dream bass right there, sadly funds won't allow. GLWTS. -
Collection prefered BL6 6NN. I can deliver for fuel money within reason. I bought this as a non working amp and I have repaired it. There was a small area of corrosion on the input stage possibly from liquid, I have cleaned it up and retouched the solder and the amp now works perfectly. I fix laptops in my day job so working on something big like this is a doddle, I also gave all the pots and input jacks a good clean out with servisol so they are crackle free now. I replaced the fan with a new one as the original was badly repaired. I checked all the inputs and outputs are all working as they should be, although I don't have a footswitch so I am unable to check that. It's a very loud amp when at full throttle, but there is an attenuator dial on the back which enables the gain stage and effects to be fully engaged but output is reduced for home use. Some very useful amp simulators and effects, see the blurb from Vox at the end for their description. Any test welcome, I'll warn the neighbours first! Please see pictures for condition, there are some marks on the covering, The centre handle is missing but to be honest unless you are Geoff Capes I'd say this is a two handle carry and the outer two hadles are in good condition, replacements are about £7. (it doesn't stink of fags by the way) Blurb from Vox:- The VOX AD100VT packs the amazingly versatile tube sound of Valvetronix into a funky 100 W 2X12 Combo. The VOX AD100VT features the patented VOX Valve Reactor circuit that uses a 12AX7 triode vacuum tube together with an actual low-wattage tube power amp circuit, a virtual output transformer and a dummy speaker circuit that simulates the impedance changes of a real speaker. It also reconfigures itself so that its characteristics are the same as the amps it’s modeling (class A, class AB, negative feedback circuit, etc.). A total of eleven coveted amp types are provided. Starting with the classic AC30 and ranging from vintage to modern, higain to clean, a variety of amp models are built-in, giving you an incredible range of sound-creating potential. Nine standard effects indispensable for any guitarist are built-in. These include auto wah, compressor, phaser, chorus, flanger, tremolo, rotary, delay and reverb. With the addition of combination-type effects, you have a total of eleven effects to choose from. The Vox AD100VT lets you adjust the output wattage from 1~100W so you can lower the volume without losing the sense of drive that’s unique to tube amps. You can get the great distinctive tube sound at a volume that’s appropriate for any location. Vox AD100VT main features include: * Number of amp types: 11 * Number of effects: 11, Noise reduction: 1 * Number of programs: 11 preset, 2 channel. * Input/output jacks: Top panel – 1 x INPUT. Rear panel – 1 x FOOT SW , 1 x LINE/ PHONE, 1 x LOOP RETURN Jack, 1 x LOOP SEND Jack, 1 x EXTERNAL SPEAKER OUT * Power amp output: maximum 100W RMS @ 8 ohms * Adjustable Output Wattage * Speaker: 2 x 12 inch VOX oringinal 16 ohm * Signal processing A/D conversion: 24-bit, D/A conversion: 24-bit, Sampling frequency: 44.1 kHz. * Power supply requirements: AC, local voltage. * Power consumption: 100W * Dimensions: 55.3cms (21.77") (H) x 68.4cms (26.93") (W) x 26.8cms (10.55") (D) * Weight: 29kg (63.93lbs) -
Lee Sklar's Frakenbass would be nice if such a thing existed.

Added some stacked pots and knobs to the bb425 today for 'fun'. Interesting variations available and just replacing the pots from the originals has whipped a few electrons into line as it does seem a bit more presence/brighter. I went with my usual 0.1uf so I have sparkle down to pure mud option. I changed the switch to after the pots so I have independent control on single pickup selection. Centre needs a bit more work as I think might have to fit some resistors for prevent the volumes fighting in the centre position. But happy with the experiment so far. Any one else tried this?

OK I'll own up 🤣

🤯 Looks better in real life than in the photos! GLWTS -
Purists avert your eyes! I found the stock bridge pickup a bit anemic and noisy in the bb350f. The pup route is not standard though as it has rounded ends rather than squared like a Fender. I had an Enwhistle jbxn lying around so I printed a new pup cover for it to adapt to the Yammy rout! I might get closer for the exact holes at some point but this will do for testing.

No, maybe one day. My ability on the bass doesn't really justify it at the mo having played rhytm guitar for many years bass is quite new to me and revived my interest in playing music. I have a bass for every occassion right now while I find my sound. A BB425 (rounds), BB350f (Flats), Ibanez 305 (flats) Fenix short scale and a MIM Precision I have on long term loan. If I can't get the sound I want out of that lot it's down to my technique, the rest is just gas! Glad it went to a good home, or I might have been looking for a new one!

So glad you picked this up, I had an attack of the 'raving must haves' had the message primed and ready to go but this bb shaped hole wouldn't sit nicely in the finances!

Here's the paint job on my Pacifica that a friend who is a local artist did for me in lockdown. I'd love her to do bb350f too but I'm not she'll have time now.
-
Thanks, they would look great but won't fit on the solid shaft of the tone pot I put on (I don't think).
-
Oooh OK, got any pics? I think i might need to go all grub screw to get a matching set.
-
I think it's fair to say this is a heavy relic! Picked this up from Andy Travis over the weekend and put it back together with some new wiring for VVT and a push pull capacitor selector. Yet to do a proper setup but sounds great! Is it possible to get a matching knob for a solid shaft rather than knurled?
-
I'd love a fretless 5 BB is there such a thing?
-
Are you selling the contents of the Norfolk Bass museum! Lovely basses you have up for grabs. -
I got a right on cork strap. Comfy strap, good width, looks cool to me. They sell than at scan.co.uk which is local to me and didn't break the bank.

I have a fenix short scale and it's a great bass. Only one pickup on it but my pots are volume and tone. I would guess it's the same on yours with a pickup selector. Guitar electrics are simple and cheap to fix (on a passive bass) so long as the pick up is good. Its an interesting double P pickup like Lee sklars frankenbass. I'd say 200 yo-yos is about right if it plays ok and truss rod works.
