Master volume for JTM 45 circuit?

Post by hotrod » Tue Nov 10, 2015 1:35 am

Hi guys, new to this forum, I'm planning a JTM 45 scratch build and was wondering if you guys have recommendations about adding a master volume, what type, how to implement it (or better not to...?)?
What's the word...?

Any advice and opinions appreciated, thanks!

Hi,
IMHO, I've been very pleased with my PPIMV.
I used the instructions found on this forum.

I tweaked the meg resistors and got the thing
to 1% of 220k on both pots, but I'm kinda of particular
about that kinda stuff. I think it's a very welcome addition.
:)

Nice thing about experimenting is what you learn and
with the exception of drilling holes in the chassis that can't be
undone most everything else can!

I can help if you with question, let me know.

The PPIV Master is a great addition.
All the way up, out of the circuit. To me it's a no-brainer, and so inexpensive.
Having tried both the standard Rich Mod, and the Lar-Mar, I prefer the former.
To each their own, but neither will break the bank or your amp!
