Instrument preamp with parametric EQ.

The SansAmp RPM is a versatile instrument preamp with parametric equalization and SansAmp technology. This single space rackmount model was adapted from the SansAmp Acoustic DI pedal, with the addition of a Drive control, and redesigned as an expanded multi-instrument tool. With a sweepable, semi-parametric EQ and variable gain, the SansAmp RPM is a supercharged tone shaper for any signal source. Partner it with a SansAmp RBI for the ultimate bass pre-amp system, or with a SansAmp PSA for total domination.

Drive adjusts the overall amount of gain and overdrive. Active Bass and Treble controls cut or boost ±12dB Mid Shift is a parametric EQ control that allows you to select the center frequency of the Mid control. Its sweep ranges from 170 Hz to 3.0 kHz. This, then, enables you to notch out any specific frequencies that may be causing your instrument to feed back. Mid is also an active tone control, cut or boost ±12dB. Blend allows you to mix the direct instrument signal with SansAmp Tube Amplifier Emulation circuitry. Individual Level control for the XLR out to optimize your amp's output relative to the P.A. system. Effects Loop with Mix 50/50 switch to configure in series or parallel. 1/4" rear input and XLR output with selectable levels. Buffered uneffected XLR output to run a dry signal to a separate channel. Footswitch input to engage unit. Footswitch output to chain and toggle between another SansAmp RPM or SansAmp RBI.

A supercharged tone shaper for any signal source! Call or click today to order.

I just received the SansAmp RPM today and it is a very great sounding amp. It gives you a lot of distortion and punch, and my basses sound great through it. Also, I looped the SansAmp RPM to my SansAmp RBI and they both sound great together, and you get a lot of control of your sound. Great product, I highly suggest buying this.

Best bass head ever

I got the sansamp RPM because of the parametric mid control. That knob is priceless. I use this and a power amp as a bass head and there is more EQ changes in slight adjustments of that knob than in most 10 band EQ's. Also the tube sound of this thing is right on, I never thought I'd use anything but tube heads but this thing sounds as good or better then my tube heads. Good job Tech21 no wonder Geddy Lee uses this thing.

I've had the RPM for about a year now and here are the pros and cons. First: my set up is the RPM through a MXR 10 band eq through a rocktron velocity through a vox 2x12 v12bn through (guitars) PRS Mira, 85 blue flower strat, j. mascis jazzmaster. PROS: One of the best straight up distortions I've ever played or heard. I just bought the Fulltone Ultimate Octave and it just doesn't compare. Though it is a fuzz/distortion. The mid shift is what is most impressive. (There are guidelines in the manual but) For a Fender tone: Mid shift about 400hz. A nasty Vox tone about 550hz. For a Marshall about 1000-1500hz and the SVT around 2300hz. The drive makes these things setting work. With that said what tones can't you find on this thing? I would NEVER trade or sell it! Effects loop, second input 0db to -20db (nice when recording to the board) dry feed, ext out, and XLR sansamp or direct. It actually cuts and boost bass and treble from 12:00 (80hz bass, 3.2khz) CONS: no reverb or any effects (buy yourself some good pedals) Other than that its one of the best investments I've ever made!

Unbeatable Sound

I replace my old Sansamp RBI with this one bacause the RBM has the midrange controls. This bad boy is awesome, You can dial in any tone you looking for in no time. If you're looking for something to help your amp with getting that live sound you can do it with this one. I have been using Samsamp for over five years now and will not gig without one, I keep the smaller one in my gig bag for went I don't have to bring my rack gear. It's a must for every bass player that looking for a warm piano sound without that Hifi tone. Beware once you use the Sansamp RPM you'll never going to be without one. Just great...

I have this preamp as well as the RBI, and if I had to pick one, I would choose this one over it's more popular brother. Contrary to popular belief, it's not an RBI with a parametric mid control. The gain and EQ structure are quite different. This unit is darker sounding than the RBI and has a lot MORE gain available if you want it to. Even with the blend at full, the tone is not nearly as scooped as the RBI, and it doesn't have the excessive high end clank that the RBI is prone to if you turn up the presence at all. The mid control is great and really helps the unit cut through the mix. Glad to see it back at this site. One heck of a preamp for the price, very flexible connection options.
