Ok, where could I find more info about this particular amp ? I'd like to turn my 67 Superbass into "your" amp (if you don't mind)

Thx Roe.

So it's basically a Superbass ? There's no bright cap ?

Ok, I thought so.

Do you remember which was used on the video ? 500 or 5000 ?
I might have both anyway, I guess I'll just stick with whichever I prefer.

Thanks for your help, Roe.

Ok, thanks Roe.
I tried a silvermica 5nF and quite liked it but I'll check if I have a ceramic one.
Anyway I prefer the amp with a bright cap.
