Hi, I think this was a common post in the early days !
I solved it by thinking of the problem the other way up ?!?! i.e. instead of 'boosting' for the solos, 'cut' for the verses !
I have my M13 set-up with the last column lowest switch as a 'volume' control set at 80%. and I leave it turned ON for most of the time. I've set the two other buttons in that column to effects that I normally add to a solo (slap-back echo and reverb) - so now I have the volume switch ON for the verses (80% volume) and then which ever button I press in that column adds 25% volume and the solo's effect (if desired) . Pressing the lowest button again turns then effect off and reduces the volume by 20%.
It works well for me, though I ought to say that I have the M13 set-up using the '4-cable' method, so this volume switching comes AFTER the Pre-Amp. A lot of valve amps will add greater distortion to greater input volume, so boosting the volume prior to the Pre-Amp will change the tone as well as increase volume.
Good luck hope this is useful
