I did a boothill last week or so and was very happy with Dave's service. Tranny's came directly from classic tone (best price/reputation ratio I could find) and I made sure to grab the output tranny with 4/8/16 ohm taps. The amp sounds fantastic un modded but I will be adding a switchable (on or off) master volume for the sake of playing at home. I believe you referred to this particular mod from robrob's site. I totally recommend it and it would make sense to just do it while you're already there. I love the range of saturation allowed by the volume controls but in terms of loudness, its essentially on or off so the master volume would be the icing on the cake so long as it's switchable so not to disrupt the ability to operate with the original circuit. As far as the board goes, I'm with clintj and sacDAve on the turrets. My boothill came with a turret board even though its listed as an eyelet on the site. Just Think, a Turret would also make it easier to alligator clip in some of the mods you're considering without heating and reheating components. That way if you dont find them necessary, just unclip and rock on.
