Preamp for Yamaha BB2004

[tom.android]

Hi all,

 

Considering trying a different pre in my BB2004 for 2 reasons:

 

a) I want an active/passive switch

b) the mid cut switch & knob on the stock pre is pretty useless for me

 

So I’m looking for a 9v pre with the following controls: volume, blend, bass, mid, treble, active/passive switch. Functionally the same as found on the BB734/735a. Any recommendations?

 

Thanks,

 

Tom

Oh! Also an ideal feature would be for the treble control to function as a tone when in passive. Basically I want the same as in a 735a.

I would suggest a Glockenklang 3 band, which does everything you asked for but the active/passive is a pull/push on the volume control so would leave a hole.

I've got Glock's in 3 basses and love them.

Thanks for the tip. I’d prefer to have the switch rather than push pull given the choice. Is there anything out there?

There are quite a few pre-amps that come configurable, ie the pre-amp capsule with a bunch of wires and you can wire whatever pots and switches you like.

Bartolini, Aguilar, Darkglass to name a few, but none give you a passive tone control option as standard.

That said you can add a passive tone to any pre-amp but that would be an additional pot.

You could use a stacked pot for 2 of the bass/treble/middle controls and then add the passive tone that would work in active or passive mode.

Hey, it's been some time.

Did you replace the preamp after all?

 

I love the stock preamp on mine.

As a matter of fact, it's the bass that's been on my stable the longest - got it from a yamaha endorser in 2008, after seeing nick fyffe playing live with those for Jamiroquai.

 

It's got 11 year old chromes, the same set since Jan 2012.

Its a deep mean thumpy funk machine.

With this very old set, the mid-shift-thing knob it's really useful to notch the right freq for the mix.
