Xotic BB clone SOLD £45

[paul_5]

Thinning out the herd, so offering up my home made Xotic BB Bass preamp clone.

 

It's had a few mods (enhanced low end and switchable clipping diodes - Silicon or Germanium) and is a great sounding pre. Capable of low gain 'grit' right up to silly amounts of filth with a 2 band Baxandall EQ. 

 

True bypass, 9v DC adaptor power only with velcro on the back.

Price includes P&P to mainland UK.

I am curious by this wee pedal. What kind of low end response are we talking here? Is there any significant loss? 

Cheers

[paul_5]

None,  I think the original schematic called for a 47nf cap into the feedback loop (overdrive section), but I upped this to 470 to drop the frequency of the HPF into the filth section, so it delivers full range overdrive instead of chopping off the bottom end. 

The input cap has been increased too, for the same reason. 

The EQ section has also been 'fettled' to increase the low end (this comes after the overdrive section)

Any chance of a gutshot please?

[paul_5]

Certainly. 

Upon closer inspection it's got 2n3106 Germanium transistors instead of the 'vanilla' 2n5088s and a Burr Brown OPA2136 opamp instead of the standard JRC4558 on the EQ section to give increased sound quality.

Here's the back of the board:

Looks good, I'll take it if you're ok with PayPal.
