Dynamo was started in 2009 by Progressive Metal Guitarist/Engineer Ervin Williams from a concept in the recording studio to use small hi power 1x12 ported enclosure loaded with a 300w EVM speaker to handle a high level of power from a 100w head. This tone weapon was so effective in recording a monster wall of sound to a large diaphragm microphone, we wanted to build a 2x12 version to use live on stage and as a compact solution for tight spaces and limited transportation room. To effectively push a pair of 300w speakers we needed a higher power amp so we started R&D to design a high gain 2-channel JCM800 based super lead with a 200w power section. After 2 years of development, Dynamo dropped a 200w TONE BOMB and quickly attracted a lot of attention from major artist, touring professionals, and made a major impact in the industry.

Each Dynamo amplifier is hand built one at a time in North Texas with the finest components and materials available. We evaluated every single component in designing an amp to find better technology to explore new levels of tone to enhance the classic tone we already love. We use audiophile grade components that can cost up to 10 times the price of standard grade components. The result is greater sonic clarity and definition, lush tones, better sustain, more responsiveness, and lower noise. We use Toroidal Power transformers on most of our models and they provide a cleaner and more efficient power supply that runs cooler, less noise, and greater peak power. A minimum of twenty-seven man hours goes into each amp to assemble, hand solder, hand wire, and test each unit. The chassis is manufactured locally at a CNC water jet facility and then welded, powder coated, and silkscreened. The Cabinets are either built in-house or by local custom cabinet mill. Each amp is covered by a lifetime warranty for workmanship and defects.
To Order and Lead Time
The general lead-time for most custom amp builders is 8-12 weeks and sometimes longer, and for that reason they usually require a 50% deposit until your amp is ready. Here at Dynamo we try to anticipate and preorder our longest lead time custom made components (usually Transformers) to have them on hand or in production to reduce the typical build time down to 3 to 5 weeks.  For this reason we request full payment via our online store and within 72 hours of your order, all components are allocated and ordered to immediately start production on your amplifier. Should any custom components be backordered or we do special custom shop jobs such as European voltage units, we will then require a 50% deposit and allow up to 10-12 week turnaround with balance due when completed.
