Yepp, I know LiveSpice and using it as a for my pre-alpha circuit prototypes. I design very unique hybrid design tube overdrive pedals, using various concepts, either a JFET-Input stage following up with a 12AX7 tube or an op-amp stage (TL071 or CA3140). Tube is running at 200-250VDC by a SMPS based on a MC34063 Boost-Regulator.....
Some of my amp design collegues didn't like the approach of using digital technology for circuit prototyping.......
The procedure is always the same - first, there is the calculation state - calculate bias points, corner frequencies, frequency responce, signal levels (amplification factor or attenuation), 2nd is the digital pre-alphe prototype f*ckaround phase, 3rd is the analog prototype f*ckaround phase, 4th comes the print layout in KiCad, 5th is the final test phase and then we got a finished product.
I did this with my very first Casanoverdrive V3 pedal in 2018/2019 then re-worked the circuit and re-released it in 2021 as Casanoverdrive Mk2 pedal. In 2023 the "Casanoverdrive Cool/Hot-Bottle" pedal will be introduced......all pedals have various operation modes and a very clever guitar amp correction circuit to match the tone in front of almost every guitar amp
I also use Richard Künnel's book on PSpice circuit simulation for some alterations.....
and here is the digital pre-alpha prototype of it (input stage is a TL071 following up by a single 12AX7 tube) - I use my audio workstation (10th gen intel i7 CPU - 10700k), RME audio interface into the clean channel of my MesaBoogie Mk3 (1x12" EVM12L) combo as reference
