My first profile! Of the amp that cured my GAS (until the Kemper came along...) I'm not sure how to post link to specific RE but name is "MORIN MOD JCM 800".
Base amp 1982 (vertical input) 50 watt Marshall JCM800. This amp was one of Mike Morin's last mods as the parts he uses are unavailable. He's a complete tone freak and this represents hours of hot swapping components until the amp grew huge fangs. Aggressive mid range with exceptional string definition. Crank the gain up a bit if you need to...
For some reason the cab we used to make this profile, an early 70's pre Rola 1960B (with original speakers), has created crazy good (to my ears) cab which I've been using instead of the Tils mixed 013 and 020 .... try it and let me know!
