Quote from: phatt on January 07, 2018, 08:33:31 AMHi Dazz, Regards Tone stacks link;Be aware that you will need a gain stage to make up for signal loss.Most of those tone circuits are passive and suffer from insertion loss,, meaning a 1 volt signal swing at the input can be reduced by as much as 70%,,so you will have to make that up with another gain stage.You will need to do some research and better still make a prototype FIRST. (hint)An active tone circuit does not suffer insertion loss but they sound a bit different and the classic passive tone circuit were well suited for guitar tone, but both will work ok if done right.Phil.

So IMO tiss a bad idea for an amplifier circuit.I'd suggest you build a simple preamp with a tone control then into a power amp.LM1875 chip will give you 10~20Watts,,depends on PSU.If more power,, then LM3886 will deliver 30~50Watts, again depends on the PSU ability to supply the grunt to drive the power stage.If this is your first venture into building these circuits then keep it simple otherwise you will be stuck when something goes wrong.I learned a long time ago not to build a circuit if I did not know how it worked. 8|Phil.
QuoteA simple preamp would just be your favorite distortion effect pcb mounted in the same housing with the amp
