If the Fender trick uses an isolating transformer, the output will be balanced. It will only become unbalanced if you connect to an unbalanced input.

Can you send a picture of the insides.

[quote name='Jabba_the_gut' timestamp='1456257108' post='2987209'] I've looked and found a couple of things that may be of interest for this type of set-up. John East does a module that sounds like it would do the job 'MPM-01' but I've also found a website '[url="http://www.cafewalter.com/cafewalter/fetpre/index.htm"]Cafe Walter[/url]' that has a piezo circuit. [/quote]Walter Harley of Cafe Walter is a great guy. Email him saying what you are trying to do and he will advise on any mods to that circuit. Hi whole site is worth a read.

Ashdown and Alex are right but the only way to ensure that an amp has s usable volume control all the way up is to match the bass guitar to the input gain of the amp. Of course some amps ( Ashdown especially ) have some form of input gain or attenuator and arguably the best way to set it up is using the much maligned VU meter. This is exactly what a good sound tech would do with a channel strip on a mixer. Also remember that the minute you put stomp box on the floor, your gain structure is screwed.

I believe the three Musketeers are doing a 2x10 build soon so wait a little while and you will benefit from their knowledge and experience.

[quote name='Hobbayne' timestamp='1456269827' post='2987365'] A few years back, I was busy lugging my heavy old Trace combo from gig to gig, an acquaintance of mine told me he was thinking of trying out this new amp by someone called Mark Bass. Never heard of him I said. It will never catch on..... [/quote]Maybe it is me but Mark Bass seem to be on the wane too now.

I like the Gotoh Machine heads too. The Resolites are on a par with the Hipshit Ultralites but the GB 707 are only a little heavier yet much lower cost, The difference is that the GB 707s have metal tuning buttons and the Resolites have (epoxy) resin. If you go Hipshot, make sure you get 1/2 spindles. Some are 3/8 and that would mean a lot of drilling and filling in the headstock.

Heft is an unmeasurable parameter only present in Valve Amps. It is proportional to weight and the real subtlety of heft comes from the light of the valve heaters.

The only way a pickup can go "wrong" is open circuit, that is no sound at all, or short circuit where the signal would be reduced to some degree. Clearly both those problems would affect all strings. Having written this though I have thought that is the pickup is ceramic or another bar magnet and it has broken, with part falling away from the pickup. Them the poles would be come demagnetised and the volume level of those strings would be much lower. So go ahead restrung so that the strings seed opposite to the way you normally have them. This will tell you wether the PUPs are at fault,

I would guess that that uses one of the NXP, Texas or ST chips. I cannot see a discrete circuit being that compact. Of course that does not answerr the question.

Find out the spec of the fan, voltage and airflow. It is usually printed on the fan. Then find a new fan to relaxed the one you have. If you can get a Panaflo fan NOS use that otherwise a Papst or some of the better Sunon fans would be OK. One other technique is to use an overrated fan. Cloud do this in their PA amps. Running a 24 volt fan on 12v will mean it runs slower and quieter and lasts a Lot longer. One thing to beware of. Do not go above the maximum voltage as fans are easy to burn out if you do.

Thunder 1A is a weapon of mass destruction when used actively.

A lot of respected poeple say that the valve sound comes from the power section. However even Ampeg use solid state in the SVT 3 series and In their pre amps they used real inductors for the tone and maybe that was what people rave about. In my opinion all these bits are components and it is in the lap of the gods and the skill of the designer that determines what sounds good.

Phil is it the usual 250W into 8 or 500W into 4 with an extension cab?

[quote name='Bill Fitzmaurice' timestamp='1455651857' post='2981209'] No doubt. The things some people will believe defies explanation or logic. Donald Trump as President, for instance. [/quote]Don't joke Bill, that is too frightening to joke about.

[quote name='fretmeister' timestamp='1455649490' post='2981166'] There's a guy on another forum who claims he can hear the difference in his hifi depending on whether the IEC power cable is straight or curved. [/quote] My brother has the same psychiatrist as him and I believe the same medication.

[quote name='sunburstjazz1967' timestamp='1453586936' post='2960914'] But the signal can be processed with much more expensive eq kit than we tend to have in our amps, by the time it hits the monitors the flub and wasted power that we feed our bass cabs can be removed giving a monster bass tone right in your face. [/quote]This leads on to another hobby horse of mine. if the Sound tech takes out the sub 30-35Hz crap that many bass amps put out that will be one of the reasons the Floor monitor sounds better. It is an HPF and they should be fitted to all bass amps. However most will be less than ideal for bass. As for IEMs, it makes sense for vocals but not for bass. Remember that your back line is a part of your instrument, like the body on an acoustic guitar.

Yes I saw something about new Blackstar Bass offerings.

[quote name='PaulWarning' timestamp='1455711784' post='2981662'] yep, my rumble is the same, I always have my input gain turned all the way up (passive bass), it's a mild input gain which really is the way it should be, they're meant to level out signals from the bass not act as a volume control [/quote]Got it in a nutshell. it is like a variable active/passive switch or hi/low. Input sockets. It is not designed to cut volume to zero but to the optimum for your sound and bass.

There is a list of BC members that will help other BC members will setup and small repairs at the top of the Repairs And Technical forum. OBBM in Farnham seems to be your nearest or you can check the list for your self. http://basschat.co.uk/topic/277468-bcers-prepared-to-help-fix-a-bass/

If you are up for some DIY the pre EB Music Man Pte amp is hard to beat and the batteries go on forever, A lot of the two bands sold by the pick up manufacturers are based on or are direct copies of that Music Man design. David at Retrovibe sells them for £40 at http://www.retrovibe.co.uk/stinger.html fully assembled. The only problem is that the stingray pre was designed for a single pup so you can either connect it after your current passive wiring or fit an M law blend pot, then feed the preamp.
