The RTO is an amazingly amp-like overdrive. While many companies claim to offer “amp in a box” pedals, the RTO is in actuality a tube preamp circuit in a stand-alone stompbox format.

The RTO700 has all the tone and responsiveness of the best boutique tube amps.  From bluesy overdrives to the elusive “Brown Sound” and beyond, all can be easily achieved with any amp at any volume when using the RTO.

Regardless of its control settings, the RTO reacts like a tube amp, cleaning up when you roll off your guitar’s volume and effortlessly tracking the most intricate picking nuances.

The secret to the RTO700’s amp-like feel is the absence of clipping diodes in the circuit.  Instead, the RTO features three cascading gain stages with an extremely high output level.  This configuration combined with the placement of the tube at the end of the circuit yields the warmest, most authentic tube tone possible.

Higher gain settings can be kept tight and noise-free using the RTO’s switchable Noise Gate with variable Threshold.  The gate itself is incredibly responsive and tight, with none of the false-triggering and “sputter” common to other gate pedals.

The RTO’s 3-band EQ circuit is incredibly versatile and can literally dial in any tone imaginable.  With zero frequency overlap, all three controls are highly interactive and make even the slightest of tone tweaks possible under any playing situation.

The RTO700 features Mechanical True Bypass switching using a 3PDT for the cleanest bypass tone possible.  The RTO comes complete with the Maxon AC2009 9-Volt power supply, an auto sensing digital power supply that can be used anywhere in the world.

Hands down, the RTO is the most amp-like overdrive pedal you’re gonna find, regardless of price.


The RTO700 gets its amp-like tone thanks to the absence of clipping diodes in the pedal’s circuit.  Instead, the RTO features three individual amplifier stages that are cascaded into one another, and all distortion depends on the amplifier gain.

In general, overdrives and distortions that have clipping circuits do not have high output levels because it is restricted by clipping.  The RTO700 has a very high output level, which allows it to drive the guitar amplifier being used, resulting in more authentic tube tone.

The RTO features an In-Rush Current Control system - As soon as power is applied to the pedal, a small current is applied to the tube and begins heating it at a very low voltage (much like a tube amp standby switch).  This system dramatically extends the tube life.  Once the pedal is engaged, 12.6 VDC is applied to the tube heater.

The RTO700 features mechanical true bypass switching via a Fujisoku 4PDT switch.
