probably one of the first botique style amps, built like a ham radio.  Mullard 12AX7's from India and Japan, big bucks nowadays,

but there is a 12AU7 driving it which has a lower Rp,

room mate of Garnet amp owner likes amp so much that he pays 100 bucks shipping charge to have another Garnet SessionMan
amp delivered to the same household,

this amp has a different preamp schematic, not found anywhere online,

so we sketched it out and did some testing,more like a Fender tone stack,

we also have what might be one of the first switchable boost amps on the market, notice the midrange circuit on the effects channel,

works good but needs a tone mod to bring back hi end when in solo mode, this would be tweaked nowadays,

there is also a boost sw on the master
