The MOD102+ expands on the same all analog vacuum tube classic American circuit design combined with a British style Class A output section as the Original MOD102 with some much added special “+” features. These special features include a three position progressive toggle switch for off-standby-power and additional push-pull functionality for each control - pull out the bass control knob for “mid boost”, pull out the treble control knob for “bright”, pull out the volume control knob for “turbo”. These new features and a JJ ECC803-S (a long plate 12AX7 known for its complex mid range tones) allow for a wider variety of tones and extra control for the user.

Product Reviews
Nice little kit! Instructions are pretty clear and it's certainly not overly complicated to build. Having some amp repair/building experience helps, but I'd say even a beginner could buy this, build it, and be playing it within a day or so. Once built it sounded pretty good as well. Fun to swap tubes around, substituting the 12AX for a 12AT, AY, or others. The 'effect' changes on the pull switches are pretty subtle, so don't expect anything dramatic there. But, the amp makes a great platform for learning, and even 'expanding' from the original design. I've put an EIA connector in the back of mine so I don't have a cord sticking out. I put some tall 'feet' on it so it would clear a speaker box handle. And, the power transformer is suitable for adding a 6CA4 rectifier, which I plan to do in the future. I'll have to move the filter capacitor section around some to make clearance for the socket, but it's a 6 volt 9-pin rectifier, so will work perfectly in this amp. I might even 'upgrade' the output transformer....or play with some yellow jacket type adapters to try a different output tube. In all, a lot of fun to build, sounds great for what it is, and I'm very glad I made the purchase!! A 'GREAT' value!!!
