hello!
I'm in the middle of designing a preamplifier circuit on multisim to go in an stomp box for bass guitar. I have two OPA627AM op-amps for the peak/notch part of my circuit but I was hoping to replace them with thermionic valves. I have two 12AX7 valves that I've noticed have a pair of triodes inside. Can I use one of these valves to replace both of my op-amps?
If so tell me how! and, if not, do I need a different type of vlave to do the job? I was initially gonna keep the valves for a 'drive section of the pedal but I haven't figured out how to do that yet. Any advice on perhaps using the valves as an intentional overdrive at a stage after the preamp section (and keeping the op-amps in the preamp stage as they're of rather high quality anyway) would be appreciated too!
Thanks!
