zapp Posted January 9, 2014 Posted January 9, 2014 I recently bought Richards' Valenti J4, lovely Bass. Now that I've had a chance to play around with it I'm considering changing the pre amp. It has an OB-1 with a pull pot for passive mode but no control over passive tone. I'd really like to be able to roll off in passive mode as I like this sound. So my question is, does anyone have any suggestions/experience with pre amps that have this sort of control? I've had a look at the East J Retro Deluxe and it does seem quite appealing. Quote
LukeFRC Posted January 9, 2014 Posted January 9, 2014 that bass also has a voltage multiplier fitted to run the preamp at 18v I'm glad it's found a new home Quote
BassBunny Posted January 9, 2014 Posted January 9, 2014 Think you have answered your own question. Great pre-amps and the passive tone control is very effective. Quote
zapp Posted January 10, 2014 Author Posted January 10, 2014 .....Looks like I'll be giving Mr East a shout then. Quote
Nino Valenti Posted January 18, 2014 Posted January 18, 2014 The bass can be modified to be used with a passive tone control. The bass and treble can be put on one stacked pot and a passive tone with a push/pull for preamp bypass can be added. Quote
zapp Posted January 19, 2014 Author Posted January 19, 2014 Thanks Nino, I'd really like to try that first. Lovin' the Bass btw Quote
