Sounds like its going really well Rich! If it were me, I'd be selfish and hold out against playing bass... but that's just me. It also sounds like you're one of the stronger "I know what I'm doing with my instrument" members, so to me it wouldn't make sense to have that person moved to an instrument they are not familiar with.

Not surprised with the zoom thing... I think all those multi-pedals struggle with the transition from practice sound to going into a full sized amp at volume. I guess there's a reason a lot of the pros still use pedal boards and tube amps! I've gone through the same issue with just about every multi-effects unit I've ever owned... practice sounds fine, then you go to play live and it just sounds harsh and brittle. Oh well, if it makes you feel better, I know guys struggle even with units like the Fractal Audio AXE FX... at least there's lots of good stomp box options out there if you need to go that route. The website www.gilmourish.com has some good reviews of pedals that might fit the bill.

Keep us posted!
