P mod idea

$200 to reduce the functionality of your bass...hmmm...

interesting....

1...the redeemer is nothing more than an exhorbitantly priced buffer circuit...sure it works...but I can throw one together on my bench in about 1 hour for about $5...

2...the booster is nothing more than a simple inductor (in this case an audio transformer most likely), tied to a multi-position switch with a few caps on it (hence, a selectably tuned LC resonant peaker)...again, can be made in about 1 hour on the bench for about $15...


and why no volume pot?

other than the price and no volume pot, I like the idea...
 
Thank you for your advice.

How about replacing PRTB with HAS Sound Bass Guitar Varitone Control (Invalid Link Removed) ?

I know it's not same with PRTB, but seems interesting.

And I don't use volume control at all so I will omit volume pot.

Actually, it appears the HAS Sound vari-tone is essentially the same thing as the Villex Tone Booster…at a much more reasonable price, IMO...

since you already have the redeemer, I'm not going to point you to a cheaper alternative...though they certainly DO exist
 
I've just ordered Bass Varitone from HAS Sound, following your valuable advice.

And cheap alternative to Redeemer...

Is this it?

that's one of many...I've studied that circuit before, it's actually a very good design...it can be built into a very small package, too...

you should really have a crack at building it...I am ;)

thanks for that link...I've forgotten about it...

I'm going to do this little project :)

I have a tiny little box that I can use...I've already got some velcro on my strap from a previous buffer I built a while back (a slightly more complex Op-amp, based circuit)...

I like wearing my buffer on my strap...(short lead to the buffer, and then long lead to the amp and/or effects)...reason is, I can use the buffer on any of 3 of 4 basses I have...besides, there's no room in the control cavity of my Yamaha bass without doing some MAJOR housekeeping and a rout for a battery...

and yes, in case you're wondering...these things really DO improve the sound...I've found that it "opens up" the sound of the bass...gives it some really nice "sparkle" without colouring the inherent tone of the bass...
