    Had some gift cash, and found this used locally. Ended up snagging it for $100.

    » 5W Single-Ended, Class A
    » 4, 8 and 16 ohm Speaker Outs
    » Preamp Tubes: 1 x 12AX7
    » Power Tubes: 1 x EL84
    » Solid State Rectifier
    » Volume with 3 Band EQ
    » Pentode (5W)/Triode (3W) Switch
    » DC Power to filaments for super quiet operation
    » 15 ply (18mm) thick-void free Plywood Construction
    » 16 gauge steel chassis

    Absolutely no need for this. But, I have always had my eye out for a good deal on one. I had read how these were always built with above their price range quality, particularly the PCB board, and are extremely mod friendly.

    Though used, it is in immaculate, looks like it is brand new shape. And, I got it for a NICE price.

    It's a fun little amp. Has a bit of a JTM45/Plexi thing going. NOT a lot of gain at full volume. Vintage crunch is the best it can manage. If you want apartment/bedroom volumes and dirt, your using pedals. Good thing the amp really likes them. My Mad Professor Sweet Honey overdrive and this are a fantastic match.

    By itself you have to crank that volume up to start getting the EL84 saturated and distorting. No preamp distortion, it's all output tube.

    REALLY reacts to different tube brands. I ended up with a JJ 12AX7, because of it's higher gain. With lower gain 12AX7's you can get it to that just breaking up Blues thing at full tilt.

    Since the distortion is all output tube, different EL84s make a difference. I ended up with a GE Pulled Old Stock over a JJ (2nd place). The GE was a little smoother on breakup, though with a little less distortion than the JJ. They both beat out the Sovtek, Svetlana, Amperex made Hammond pulls, and EH. Could hear a difference with each and everyone though. Some almost sounded 6V6ish in this amp

    Pentode/triode also give a slightly different voicing.

    Already planning out some mods. I got it with that in mind, as I enjoy it. Looking to increase the gain a little, and adjust the tone stack a little bit. Might also add a MV or power scaling as well, moving the Pentode/Triode to the back.

    But then, was running it through my Unleash, so the MV may be unnecessary. Had to use the unleash, because it is LOUD when cranked.

    Congrats Cyber.
    I use mine daily. No more 3 watt its strictly 5 with a tone stack
    By pass switch and also carling 3 way. I crank the volume and use
    my dirt pedal volume to control it usually my joyo Us dream
    or vintage Od . I agree with your assessment I use jjj pre and tungsol
    el 84 outputs or JJ I didn't get as good crunch and break up out of
    Eh and some others. I also have the Bh15 it gets a little nastier
    without pedals has presence and drive but ya still need a pedal to get
    down N dirty its voiced a lil different like a hybrid vox and 74 x
    melted together great with Tele or single coils.

    Okay answer originally the idea was add gain but it wasn't working out so
    after the new OP tranny. we decided on the tonestack bypass and DB boost toggle you see inbetween MID and treble and I told Pat not to worry about
    going back 3-5 watt option I don't use it on any of my other amps either just not me to damn thin and spikey for me. So the knob is just another
    volume . The amp is void of any hiss or hum wether cranked clean or with pedals. Lead posted some pre packed mods available from mojotone I believe. and there was a guy in Arizona taking these and rebuilding them with reverb and gain and putting his name on them and selling them as his OWN creations for like 699 -750 LOL but I cant find the vids but there on
    you tube.
    thanks frankd
