I'm designing analog guitar effects. I only had a few courses in college concerning analog circuits, but if you understand the principles, it's easy to learn from the schematics available on the internet. So far I've been exploring the use of MOSFETs - I found that the 2N7000 transistor is as cheap and abundant as BJTs, so I'm using it. This type of transistor is less predictable and has a more complex working principle than a BJT, but with that come additional possibilities. My last non-idiomatic-but-working design is a MOSFET-based A-class buffer that maintains an optimal operating point using a BJT differential amplifier as a comparator for the feedback loop, maintaining the DC output before the coupling capacitor at exactly half the supply voltage. It's not linear, but that's the idea - if you plugged in a guitar to it the difference wouldn't be really noticeable, but doing the same with a bass should give a "sweeter", enriched with low harmonics tone.
