Would that be the same Fret House on citrus ave in west covina, so cal? If it is, love that place! I bought my 295 from them as a NOS unit back in the mid 90's. Still kick'n butt!
Lots of nice guitars. I have a MKIII that was a purple stripe, but i had it modded to the IIC+ spec and added the R" volume mod. Mike B at boogie fixed me up! Love that guy! Really good people,
called me to let me know when he had finished the job! I bought my MKIII directly from Mesa when I was stationed in Madrid, Spain with the US Air Force back in the mid-late 80's. Haven't had a chance to crank it up, I still live here in Madrid, in one of those high-rise apartments, and I have no rehearsal place, so gotta keep it low to keep the peace. But, it sounds like it's gonna be at killer at stage volumes! The R2 Vol mod really helps in balancing the three modes, although it reduced the fatness of the sound that it original had. I really liked that "fat", I could get a screaming rock tone with lead 1, and then with R2 get a warm, almost brown jazzy tone, with the same guitar by playing with the volume knob. The problem were the volume levels. Anyways, I'm still in tweak mode, and really can't finalize anything until I can play it a "real-world" volumes. Sorry for the long post, your mention of the Fret House, and your location (anaheim-Disneyland!) gave me warm fuzzies, I'm originally from Grand Terrace (San Bernardino county). Good Luck with your decision!
