i have 3 valvetechs now. one stock vac 50 watt (the red one) and 2 hayseed customs. rob is fantastic to work with. his hayseed series is based on the vox circuit. you can get several versions, early, late, trem, reverb, ef86, etc. i would recommend valvtechs to anyone. the last head he made for me (w+ is totally killer. the first custom head he made for me (b+w) goes head to head with guytrons, dr.z and carrs and most people prefer the valvetech. the attention to detail and fine tuning of the amps is second to none. his vac amps are of his design and can cover clean, dirty and high gain territory.
