    Sold Two Rock Opal prototype!!!

    This is a very special amp! Not as compressed sounding as later TR offerings, including the Custom Reverb Sig. From an email to the owner (for whom I am selling the amp) from Chad Mangrum: "Yes what you have is the precursor to the Opal amp - which was our "Wireless" amp. One of my favorite...

    Sold K&M (Two Rock) LTD amp head - SALE PENDING!

    Wonderful amp! Serial #04 - making it one of the first run of this model.

    6L6WGB, 6L6GC, 5881 - Differences?

    If your LTD is not one of the first 5 or 6 it should have a Hi/Lo standby switch. If so, the Hi setting supplies about 405V to the plates - you're safe. They designed this amp to handle 6V6s on the Lo setting; the first 5 or 6 were cathode biased and one power setting with about 360 plate volts...

    PSA - linguistics

    This is something that always bothered me about the guitar community. When you make a verb past tense like "relic", it becomes "relicked", not reliced. Reliced means to infest with lice again. panic/panicked traffic/trafficked shellac/shellacked relic/relicked Here's the rule: "go on a...
