K-MOD103 Effects Kit - MOD® Kits, The Wave, Spring Reverb
The Wave is a versatile stand-alone, tube driven analog spring reverb unit kit. It can be used in front of your guitar amp or as a line-level analog reverb effect for the recording studio. Two controls allow you to serve up a wide range of wetness from just a touch to over the top psychedelia. The "dwell" control adjusts the input signal level driving the tank and the "reverb" control adjusts the level of output reverberations from the tank. The Wave's all tube design utilizes four dual triode vacuum tubes - three 12AX7s and one 12AT7 - and comes with a MOD® three-spring reverb tank. MOD® reverb tanks are deemed the closest to the original reverb tanks from the '60s made today. The Wave's reverb function can be switched in and out pop-free via the front panel toggle or with a footswitch. Footswitch sold separately (see P-H470 for compatible footswitch).
