The CKK Electronic Frogman Tremolo Pedal is designed to get your guitar tone bouncing around the stage. It is an optical tremolo design with an organic response and a wide range of tremolo tones.

Optical Design

The Frogman uses an optocoupler to recreate the tremolo sound of the classic Fender Twin Reverb Amplifier. It can run with a square or triangle wave letting you achieve both smooth and stuttery tremolo sounds. The pedal gives you a large degree of control over depth and speed, delivering a wide range of tremolo sounds. The optical design provides less colouration on your overall tone so you can be sure that the frequency response of your guitar will remain the same. Whether you require a subtle thickening of your sound or a full-on psychedelic sound effect, the Frogman won't disappoint.

Rugged Design

The Frogman is a rugged pedal with a metal chassis and is built to last on stage. It provides a quality tremolo sound produced by an authentic optical circuit at an excellent price point.

CITES regulations concerning the export of items containing certain woods affect any guitar sold ouside of the European Union and which contains any quantity of either Rosewood or Bubinga.  In these cases, an additional charge of £80.00 will be levied per species after the sale to pay for the required re-export certificate.  There will be a delay in dispatching any guitar containing either Bubinga or Rosewood of up to 4 weeks while we obtain the necessary certification for export. As the charge is per species, where a guitar contains both Bubinga AND Rosewood, the charge is doubled to £160.00.  We will contact you following your purchase of any guitar containing a controlled wood and advise of the charge once you have placed the order.  You can make payment for the charge by sending a Paypal payment to us at: sales@fxpedal.co.uk. 

Note that CITES only applies to guitars containing Rosewood or Bubinga that are being exported outside the European Union.  Guitars being delivered with the United Kingdom or in the European Union will be dispatched as normal.
