For blues guitar, start with the gain low, the volume at the level you need, and the bass and treble near the middle, with the amp set to a clean voice. Raise the gain in small steps until hard picking adds breakup, then back it off until soft picking stays clean. Add reverb in a small amount after that.
Set gain low and volume
Turn the gain down and set the volume to the level you need, then set the bass and treble near the middle. Choose a clean voice or amp model as the starting point, with no effects on. Play a few notes and listen for a clear sound with no breakup before you change anything else.
Balance bass and treble near the middle
Keep the bass and treble near the middle and move one knob at a time in small steps, playing after each change. If the low notes overpower the high notes, turn the bass down a little and play again. If the high notes stand out too much, turn the treble down a little.
Raise gain until hard picking breaks up
Raise the gain in small steps, playing hard and then soft after each step. Stop when hard picking adds breakup and soft picking stays clean. If the sound stays broken up on soft picking, turn the gain back down until soft notes come through clean.
Add reverb and delay in small amounts
Add one effect at a time, starting with reverb in a small amount. Bring in delay or chorus only after the reverb sits where you want it, and keep each effect low enough that the notes stay clear. If the effects cover the notes, turn the effect level down before you change the gain or the tone knobs.
Check the setting the way you will use it
Play through the setting the way you will use it, and listen for breakup on hard picking and clarity on soft picking. Use the headphone output when you need to keep the volume down. Once the setting works, note the knob positions so you can return to them later.

Frequently asked questions
What gain setting works for blues guitar?
Start with the gain low and raise it in small steps until hard picking adds a little breakup while soft picking stays clean. That range keeps the notes clear and lets your picking change the amount of breakup.
Should I use reverb for blues guitar?
Yes, in a small amount. Reverb adds space around the notes, so add it after the gain and tone knobs are set and keep it low enough that the notes stay clear.
How do I stop the bass from overpowering the notes?
Turn the bass down in small steps and play after each change until the low notes sit in balance with the high notes. If the low notes fade, raise the bass back toward the middle and turn the treble down a little instead.
