Super rare ROGER MAYER triple 12AX7 all tube high voltage preamp, only 80 made in the 80s by roger himself, the man who worked on jimi hendrix's effects and amps. These were made in the early to mid 80s. These are one of the very first ever rack tube guitar preamps. Contains triple 12AX7 tubes run at vintage amp high voltages, along with 4 transformers (3 power and 1 round output) and is dual channel in the style of vintage marshall plexi/bluesbreaker meets tweed bassman, with special tone tweaks.


Like an old cranked plexi 4 hole type amp. It is not a high gain hotrodded marshall metal style, It is in the classic 60s 70s cranked vintage marshall range. Also takes pedals well for higher gain harder rock when pushed. This pack includes profiles with Klon and Noble overdrives.

Here is a quote I found from Roger in an old interview about these:
"When I started looking into guitar amplifiers and playing with them, I started making for the recording studio an item, a preamp box, that basically had a very similar front end like a classic amplifier," Mayer said, "Because people in the studio wanted to have a direct sound that they could put into the studio desk that had tubes in front of it. This was a three-tube, 12AX7 unit. Basically you had a similar circuit to a good amplifier up to the power tubes, then a nice little transformer output that went into a recording desk." - Roger Mayer

*note from Michael: Strangely 6 of the EL34 profiles show that there is no cab, but the profiles sounded really good, so I decided to include them.

Always order big!
I needed a minimum of 2 AWG wire to create interconnects between batteries in a large bank. If you note, these say 1/0 Gauge, not AWG. What is 1/0 Gauge? Who knows, it's fake. Meaningless, because it is not standardized so you have no clue what you are getting. What did I get for my 1/0 Gauge wire? Something that was in between 1 and 2 AWG (closer to 1). This was perfect for my needs because I knew darn well how big to order when they say gauge instead of AWG. As a rule of thumb: If they as gauge, order 3 - 4 sizes larger than you need in AWG. This will always net you larger wire than you need but I have never had it net me wire smaller than I needed. At the price I got it for during prime days, it was a steal for 2 AWG wire, so I win! I hope you found this helpful!

Heavy duty and has lasted three years so far
I have had this relay installed in the engine bay of my Lexus RX 300, functioning to link the front battery to the additional battery in the trunk whenever the ignition is on. The relay has worked reliably for about three years now with no complaints besides one minor comment, be careful when threading down the nut on the Low voltage side. It is prone to stripping

Heavy Duty!!
Performed extremely well. No buzzzing or poor connection. Extremely well built and has been working issue free for over 6 months! Instalation can be a bit difficult due to size and weight. Not really a problem.
