Guitarists who are looking for top quality rotary speaker emulation at an incredibly affordable price need to look no further than the Rowin LEF-3801 Roto Engine. This guitar effects pedal combines the coveted rotary speaker sound with the addition of Phaser, Vibe and Chorus effects for an expansive range of tones.

Control Made Simple

The Roto Engine by Rowin has a very simple design interface all encased in a well-built, durable aluminium alloy chassis. Some rotary speaker pedals come kitted out with more controls than you may actually need, but the LEF-3801 provides you with everything you need with three main controls and a mode switch. Its straightforward design also enables young guitarists and beginners to enjoy its brilliant range of sounds.

The main controls include Level, Intense and Speed which are somewhat self-explanatory; by tweaking each of the individual control dials you can adjust the level, depth and speed of the effects output. Rowin have also included a mode switch which allows you to incorporate three additional effects; Phaser, Vibe and Chorus.

The Roto Engine has a true bypass footswitch to engage the pedal and also to switch between the effects and bypass status. When the pedal is in use, a handy LED status indicator lights up, so it is easy to see even on a dark stage.

The pedal features two 1/4 inch jacks, one for signal output and the other for plugging in your desired guitar. A 9V DC regulated AC adapter is required to power the Roto Engine pedal (the power supply is not included).

The Rowin LEF-3801 Roto Engine is an absolute bargain in the market of rotary speaker guitar effects pedals, offering excellent quality tone at a price that suits everyone.
