[quote name='BigRedX' timestamp='1489329238' post='3256052'] Effects loops are most useful on amps with valves in the pre-amp, so that you can run the effects that sound best post-distortion in the appropriate place. [/quote] All the built-in effects loops I've ever seen have the 'send' downstream of the pre-amp in the signal path, so any pre-amp distortion is going to go into the loop.

It's going to be a challenge to find another one in the same colour!

You can, select the "Use full editor" option.

Effects loops normally run at line level voltage and are intended for studio rack effects. This is a lot higher than the instrument level voltage that most pedals are designed for. Some pedals cope with this, others don't. Unless you know the pedal can handle line level voltage, the best place for it is in the signal chain. The other thing you need to know is whether the loop is parallel or serial. Parallel gives you a blend, usually 50/50 , of clean and effected signal. This may not be what you want, for example if you are trying to compress the whole signal. Some amps can be switched from parallel to serial (Markbass LMII and III can), some can't.

I'd forgotten about Max. The SFX sound custom page does list a double bass interface which seems to do exactly what we both want - one piezo, one switchable piezo/mag, individual level controls and a phase selection switch. Max's stuff is of the very highest quality (I also have a microthumpinator) but I'd guess that we'd be back somewhere round the 300 quid mark! Be quite a challenge to shoehorn it into a 1590 enclosure. I have an LS-2 and a Shadow piezo pickup, so I'll give it a go and see if it's useable.

Good timing, I was thinking about building something similar (to balance wing and clicky piezo pickups) and had asked in DIY Effects for designs. £300 is more than I'd want to spend on this (my bass and pickup combined are probaby worth less than £300 !) and I'd want it to fit onto the bass so I can use a single-channel wireless rather than 2 cables. Schatten Mini Pre 2 https://www.thomann.de/gb/schatten_design_mini_pre_2_acoustic_preamp.htm is designed to do this, and can cope with Piezo or Magnetic pickups. I think you could do this with an LS-2 in A+B mode, you'd need a jack plug in the input to switch it on. The input impedance of the LS-2 is listed as 1 Mhz which is OK for piezo pickups. But once again too unwieldy to fix to the bass.

I have a briefcase, which is basically a bass buddy with a 100W power amp and 2 5" speakers. It's barely loud enough for a rehearsal with a quiet drummer.

Sell a bass? Sorry, not clear on the concept you're going to have to take me through this one slowly.

Thanks Charlie, I will check those out.

Can anyone point me to a circuit for a dual channel high impedance preamp with a gain control on at least one channel? I am looking for something to blend a double bass bridge and fingerboard piezoelectric pickups, without spending K&K Sound amounts.

A double bass would be so much better on every level.

[quote name='ben4343' timestamp='1488635950' post='3250651'] Having been through a similar process, I would recommend a LS2. [/quote] I don't think it will do simultaneous output to two amps. It can switch between one or the other.

I notice there's no guideline price. Should we start a sweepstake on how much it goes for?

[quote name='pete.young' timestamp='1483799789' post='3210221'] I think Al Gare is still playing in Imelda's regular band. Darrell Higham left when they split up though. I'll let you know after the gig in May. [/quote] Postscript to this - I went into the Box Office yesterday to pick up the tickets. I said to the woman at the desk "I've come to pick up some tickets for a concert in the Corn Exchange" She looked me up and down, then said "would that be for Gilbert O'Sullivan?" How humiliating!

[quote name='Painy' timestamp='1488306930' post='3247776'] I've found my Snark pedal copes with the low B better than any other tuner I've tried (and I've tried most of them). [/quote] My Snark clipon is worse than useless with a low B. TC Polytune clip is much better. Korg DT10 is great too, although it takes up a lot of space.

Thanks Platypus, that looks promising, we'll have a chat with them and see if they're happy to take it on.

Yes. Reason being that the effects loop normally runs at line level voltage and that's probably what you will get from the line out of a keyboard.

You could also try the effects return.

Gents, Need to find a clueful amp technician in the London area, to service and re-bias a Fender Princeton and fix the problems with the reverb (probably also a valve replacement). Any recommendations?

[quote name='AndyTravis' timestamp='1487978451' post='3244869'] The single cut 5 string sound gear won that round - a great bass. [/quote] I tried one of those too, in Wunjos. As you say a great bass with a huge range of sounds and very good build quality. Can't believe they can make it at the price. If only they'd done a fan-fretted version ...

Seems fine here - I'm getting a miserable 18 Mbps on Infinitiy, yet.
