Hi Maggior - Your having a good time with this - I envy you. Despite the little speedbumps it still sounds like a lot of fun. Slip's story bout the loud drummer is probably the most universal issue in live music. The guy who finally comes up with a way to control the volume on acoustic drums will be a billionaire.

Would this work for you?: When your setting levels prior to actually playing (I assume the mentor is monitoring this process?) ...have the volume on your guitar at half-way. Then, while your actually playing adjust the volume up to where you can hear it. As long as the amp your using has plenty of headroom the added breakup will be minimal. If you get the volume down signal from the mentor ... oh well, you tried.

I started doing this years ago because at jams you usually set amp levels relative to the snare drum. I learned quickly that once your actually playing - the drummer is going to "pound" considerably harder than the reference level he gave you to start. Usually, by the end of the night EVERYONE is playing louder than anyone originally intended. Oy vey. The birthplace of "too damn loud".

Hope it's OK I chimed in ... I'm following your adventure with interest because I'd love to be doing it myself. Anxious to hear your performance recording - it doesn't have to be perfect to be good listening - so relax and (continue to) have fun. Keep us posted.
