Our Services
Amplifier Design
We work closely with musicians and tone enthusiasts to design custom amplifiers that match your unique sound preferences. From circuitry to casing, every detail is carefully crafted to perfection.
Amplifier Repairs and Restorations
When we are dealing with amplifiers that fall in the vintage description things to consider are the effects of time on electronic components not just vacume tubes.
Amplifier Build
Looking for a completely custom amp? We hand-build amplifiers using premium components to deliver unmatched tone, durability, and performance, tailored just for you.
Custom Extension Speaker Enclosures
ATG can provide both open back and sealed/ported speaker enclosures designed for specific speakers. The one pictured is a ported/sealed back enclosure that houses a 12” original JBL E120 rated at 300 watts program and 150 watts continuous, 8 ohms with a response of 50 – 6000 Hz. The enclosure pictured was built to the JBL specifications for this speaker. Please feel free to provide us with your specific needs and we will provide a quote.
