Yamaha BB614/5 PREAMP with push/pull PASSIVE option £40 inc UK mainland delivery - *SOLD* £40 Suffolk

[Quent]

Hi. I’ve just had a Glockenklang 3 band put into my 2005 BB614 which I bought

from Slapmonsta last Dec. He said prev owner Shepster had had the standard preamp 

modified to include a push/pull volume pot which pops the bass into

passive mode. Apart from one older looking pot the shafts on the others

look a lot newer with bright looking shafts.

 

Spacing of the B,Mids, Treb pots on the board are 32mm and 32mm.

 

The board says Yamaha QC87550

 

This is a great option because the Yamaha pickups have legendary

power and passive tone. Note - there isn’t Tone control in passive mode but it’s

a quality sound and you can blend the pickups for variation anyway.

** The only caveat ( which Slapmonsta kindly alerted me to ) is that with full volume 

in active mode , when you pull up the knob for passive the volume drops a lot BUT

when you roll OFF the volume control just a little , the volume leaps back to match the 

full volume of active mode. ** 

None of us (owners) know why this is but it’s easy to roll off the volume.

 

 

Priced accordingly and includes UK mainland delivery.

 

I have another BB614/5 for sale like this ( another Glock mod ) which is Standard ( No passive )

so you might prefer that and it has the vol and blend larger knobs with it ( £30 inc delivery ).

Cheers. Quent.
