Shape it to your exact tonal preferences by configuring the RM100C2 with any of 18 preamps 3 at a time!

Includes all-tube Blackface, Plexi, and XTC plug-in preamp modules. A pair of Celestion G12T-75s translate all that tubal purity into rich tone! Cab comes fully closed-back with removable panel to make it semi-open back.

This highly versatile 3-channel combo melds tradition and technology. 3 independent channels can be loaded with your choice of any of the available tube preamp modules. Set this head up with tones that exactly fit your needs, then expand your arsenal anytime you like.

Enjoy the ease of replacing your power tubes anytime you like, with the very user-friendly power tube bias section. If a tube fails, no problem, the amp will kick that tube out of the circuit, and a small LED will light by the tube that fails.

Connect your RM100B to any MIDI-capable external processor and program individual effects to each channel. With the MIDI in/thru, simply select your channel and external effect, using the included RF3 MIDI footswitch. The footswitch will select both the RM100 channel and effect you want at the same time.

So, if you need the volume and power only a head will offer, choose one that will adapt to your styles.

All modules include 2 - 12AX7 preamp tubes, 3 band EQ with bright switch, and level control.

top of the line

By randallman

from independence, mo.

Absolutly the best amp I've ever had. The tone explodes on every note. very expensive, 3.5, but true professional tone & features like the paralell effects loop which allows you to dial in & out time based effects like delay or chorus ect. My band is going to freak. And it can get way too loud for band practice. Highly recomend this very versitile amp. By the way, the 3 modules in mine are all very useful & not cheesy at all. No need for distortion pedals or corny multi-effects pedals.


Excellent for blues

This amp sounds best for blues and single notes and not chugging power chords. The speakers just do not produce a good crunch but rather a bassy thud which can be remedied by lowering the bass and density feature. Still, the preamps sound best when not in full gain mode but overdriven and midrange knob boosted. One of my 6L6 tubes cannot decide if it wants to work on any particular day. I took off the back top panel and the amp sounds way better with the open back - what a surprise. I like my KH stack way better, get that!


Spent more time in the shop than in the studio

Bought it, played it 2 days, then realized the effects loops didn't work. That same night, the power/volume cut out. Took it to Randall's Authorized Repair shop in my area. The guy had it over a month. He was able to fix the power problem but was stumped about the non functioning effects loops. He had it so long, it out did the return policy. Now i'm stuck with a broken amp...and THEIR repair guy lost my footswitch!!! UGGGH!!! All I can say it sounded pretty good for a couple of days, but was not worth the stress. Working with Randall to get this thing out of my site.
