    am interested in getting something in the plexi space that has more grunt than a 45/100 - LZ to early EVH type stuff.

    I was generally trying to decide between a Metro 12,000 or a Germino HR100.

    But I have recently seen PT's clip of the Suhr SL68 and am definitely intrigued by this one.

    General question though: is the SL68 made to the same high quality, turret board (non-PCB) construction as George's and Greg's late '60s plexi variants?

    Anyone happen to have any experience across the three?

    Does a second SL68 exist? I thought it was a one-off that Suhr could duplicate. Never heard of anyone aside from Pete Thorn having one.

    it is an offering that anyone can order...of course, the only person i have ever heard talk about one is pete :)

    hence, some of my questions

    I have had the privilege of playing all three and all three are awesome, but the SL68 is the most versatile IMO. It has a full power and a variac setting on it that lets the amp "brown" out without having to rebias and it sounds spot on for the EVH brown tone. In full power mode, it get Led Zep tone easily and will still scream when cranked like a great SL. The SL68 was very quiet as well. The Suhr is also made to the highest quality parts just like the Metro and Germino. The SL68 was the one at the LA Amp show last year, I think it was Pete's amp.

    You can't go wrong with any of the three IMO, but the SL68 would be the one I would buy if I had the scratch...

    That would be it, all of them are very basic plug and play amps...

    thanks a lot!

    yeah, its funny - with these types of amp just the simple addition of the variac is the equivalent of bells and whistles :)

    i would like to see if it might be possible to get them to add a true bypass fx loop on the suhr (i think the 12,000) has this so maybe it is feasible with the circuit.

    do you happen to know how the SL68 achieves its rebias trick? although obviously tremendously cool, that is actually what had me slightly worried that we might be entering the digital/pcb realm of modern marshalls....not that there is anything wrong with that but im on a little bit of a simpler is better kick it seems.

    i actually had asked suhr but was waiting for a response...no deal on the loop, whiich seems kind of unfortunate.

    i have liked what i heard so far but thinking it would be really nice to have the loop for reverb and delays

    Line out--effects--power amp--seperate cab might be a better idea anyway, since the SL68 is intended to have the power section distorting.

    Metropoulos will build a 12000 series with a loop and a PPI master volume if you want. You can completely switch the loop out of the circuit if you want.

    In my opinion, you can't go wrong with George's stuff. The Metropoulos 12000 series KILLS, and it also has a low voltage setting where the tubes are getting about 400 volts--it doesn't work the same way as the Suhr amp, but George can build you the amp with a lot of flexibility.

    PM me if you want to discuss.

    sorry but i am a complete idiot when it comes to this sort of thing...can you describe a little more what you are suggesting and what would be needed?

    is this the wet/dry type of thing...which i hve never gotten my pea brain around either :)

    These amps just don't do well with a loop IMO. It is better to use something like the Alex attenuator and use the line out to your effects and then to another amp for the wet sounds.

    Something like this:

    Guitar>Amp>attenuator>Cab #1
    Line out from attenuator> effects> power amp> Cab#2

    This is my preferred way to do it with a Super Lead type amp. You could also do it the Eric Johnson way like this:

    Guitar>Amp>Cab #1

    Microphone on Cab#1>Mini PA board>loop send on PA Board>effects> loop return on PA board> Powered Speakers (EJ uses the Eon JBL's). Main out of mini PA board to house mixer.

    What is your experience? Particularly with delays?

    If you want a loop I can do one but it takes away from the purity of the amp.
    Also if you will be slamming the output section (most likely) the effects will be distorted which is not ideal. Really best to use a slave out (which I could install in the amp) and use a second power amp and cab for effects. That is pretty much the holy grail way to run this style of amp. I can also put in a PPI if you want on the back but again it takes away from what this amp does best. Better off using a good attenuator.
    There are NO PCBs in this amp (not that I couldn't do the same thing with them) , it is 100% hardwired and laced up old style with lacing yarn and old style hookup wire as well, uses Military PEC Pots as well, these are expensive!. Nickel plated eyelets in a 3/32" board. I find the Eyelets to be the best and cleanest IMO. No wires will ever drop out the bottom either since everything is fed thru the face and hooked back in to the eyelet. The dual bias is just that, two bias pots one for each power setting. We also etch and spray all our own plexi panels, no kit parts here and a steel chassis for this one.

    john, thanks a lot for taking the time to post here!

    i have actually received some feedback from others that loops don't seem to be a great pairing with this type of circuit - but it is AWESOME you would be willing to make that an option.

    although i have not ever used a wet/dry set-up, i suspect this might be the optimal thing to do if i ever wanted to use a lot of reverb or delay. I would be putting this through an Alex attenuator, which i am pretty sure already has a line out so i think the only things i am missing would be a power amp (and potentially a smaller cab to run it through, unless i could just use the other 4x12 in my stack and run the dry as a half stack itself).

    it probably would make sense to put a line out in the head, for potential future flexibility i guess.

    i think this amp sounds awesome in Pete's clips and the variac/re-biasing is a great feature - thanks for making it available to a hack like me!!

    I can install the line out for you but it wont have a phase switch and be transformer isolated unless you use out line out box. Sometimes that is an issue sometimes not. Here is a iphone pic of one we are finishing up.

    ah, FINALLY - a gut shot!! :)

    looks great - you actually do all these yourself John or you've got a team that works on all the HW models?

    Dry/Wet is the best way to go, IF you have a second cabinet/amp. You can also use a combo amp, running the FX unit into the FX loop of the combo (set to clean). I use a tiny Tech 21 TM-10 for FX at home with my Marshall 1959 w/ no loop. Works great, and you don't mess up the original dry tone.

    For larger venues, I would think you could use a 100 watt combo as the wet FX rig.

    I have been doing most of it but I have a guy now who did this one who is neater than I am. Everything is fully documented by me wire for wire and this kid solders immaculate.

    Hmm.. so within reason you could do different colors for the panels?
