As the name suggests - an overdrive amp, but with an incredibly clean clean tone! It can take half an hour before the amp is adjusted to its needs. Because Drive & Level from the lead channel is dependent on Gain & Master of the Clean Channel. What starts out in the beginning is rather confusing, but in the end makes an incredible number of sound variations possible and also offers the perfect match between gain and volume depending on the two channels. Very professional. The lead sound is typically Overdrive Special and has a unique singing lead sound and with an extremely long sustain. As already known by Dumble, this legendary sound comes unfortunately only from a certain volume. You can play the amps wonderfully quietly, but the full sound develops it only from Drive Level 12 clock. However, the extremely strongly engaging sound control in connection with the toggle switches can compensate for the Til very well at low volume. About the clean sound you have to say nothing - just a very big fat clean sound, with all "sparkle" -heights we know from the legendary Dumble-Amps. If the Treble & Gain-Control is fully excited, we are also here in a top-class crunch, which is extremely defined rocks. An amp that is just incomparable with humbucker guitars.

A 2x12 "Dumble-Style or even Marshall Style Cabinets are ideally suited for this amp - with EV12 Classic or a Scumback M75 / 65LD Speaker. For low budget does the WGS ET65 also.

The Dirty Wonderland has been our most popular amplifier. This single channel design was inspired from a limited edition amplifier built in 2008. We had the pleasure of spending 4 weeks with that amp, and reverse engineered the circuit and created our own version.

The Wonderland has big, sparkly clean tones, similar to a Blackface Super Reverb with a more midrange. The amp stays mostly clean, but will break up at higher levels of gain or the master volume. It has three EQ boosts (bright, mid, and deep) allowing the player to quickly select frequency boosts for different guitars or different overall sounds. When pushed with the mid boost on, you can get a sweet blues crunch with higher output pickups, and even some controlled feedback while remaining “clean”.

The Wonderland has a big, open, airy sound that is uncompressed, while staying tight and bold. It’s incredibly lush three-tube reverb makes the beautiful clean tones even better. The reverb is dialed in with two controls on the front panel, ‘send’ and ‘return’ – which act as reverb depth and level adjustments. Because of its abundance of clean headroom, the Wonderland makes a great pedal platform.

The Dirty Wonderland adds two “Dirty” switches on the back, that when engaged, give the amp more attitude and earlier breakup. We have also added a “preamp boost” toggle located on the front of the amp. The Dirty Wonderland can be ordered with a footswitch for the boost, and also for mid boost. When the Dirty switches and boost switch are not engaged, the Dirty Wonderland is stock Wonderland circuit.
