Fawn-Black 2x10 combo cabinet.

Our deceptively simple control panel starts with a single input jack and selectable Hi/Lo impedance switch for matching any unbalanced microphone.  The TONE control also features a pull FAT switch, the down position is cleaner, pull the knob for a thicker Chicago honk. VOLUME control has a gain boost pull switch, for earlier breakup or to enhance weaker microphones.  The PAD control, an exclusive feature on MegaTone Amps, allows you to trim the intensity of the power tubes to alter the amount of compression and control feedback.  Pull the PAD control for half power, to tailor your amp for smaller venues or recording.

Interview with Dale Laslie part-1

Replicate the Chicago blues harmonica sounds heard on great recordings made in the 1950's 

Inspired by the legendary Masco ME-18... public address amp from the 1950’s, a model that we have restored for many harp players with great results.  This classic amp has been re-created in a more powerful package that includes all our proven harp mod technology, built with rugged point to point construction - and we call it the WEZO ME-18. 

Are you tired of fighting feedback, looking for more bottom end, does your amp sound too sterile?  If you want a versatile blues harp amp of the finest quality, with the sound and killer looks to go with it...  then look no further! We offer you three different models, that will work for players at any level.

All models feature old-school, point to point construction for two reasons.  The most important benefit of not using a circuit board is that you can put the components exactly where they belong, so that the amp background hum and noise will be greatly reduced and the circuit will be much more stable.  The other reason to avoid circuit board construction is because they can crack due to heat and stress, and they make it harder to replace parts.  ALL the components are chosen strictly for their specific tone contribution, from the transformers to the type of interconnect wire, all makes a difference!
