The ERSO Flagship Amplifier:

Inspired by the timeless tones and response of the Overdrive Special, Steel String Singer, Slide Winder, and Vintage British amps, the REVAN 100 fuses their finest qualities to embody the pinnacle of clean and cascaded overdrive amplification.

In its pristine clean channel, experience unparalleled depth, definition, and responsiveness. With a rich, bouncy character and a gentle saturation that invites exploration, it's a canvas awaiting your touch. But that's just the beginning.

Enter a realm of boundless possibilities with our expansive cascaded overdrive channel. Tailor your tone with precision using controls that shape both the sonic character and dynamic response. Switch between symmetric and asymmetric modes to unlock distinct textures – from modded British clarity perfect for rhythmic textures to thick, symmetrically cascaded overdrive tailor-made for leads.

Designed to accompany you on musical journeys across genres and continents, our amplifier marries vintage sweetness with modern versatility. Unlike its contemporaries, it embraces the heritage of vintage circuitry while offering passive, unobtrusive options for personalized tonal sculpting.

Each amplifier is meticulously handcrafted with the finest, most musical components available – the kind that are reserved for those who seek uncompromising excellence. With a robust 100-watt 6L6 output section, it's poised to elevate your sound to new heights.

Price: $3,999


This little monster packs an unbelievable punch with the largest tone to watt ratio I have ever heard. It has super sweet cleans but when cranked, will give you a beautiful blooming and held together overdrive at a loudness you would think is coming from a high watt amplifier. If that isn't enough, this amplifier has taken what is beloved from the famous D-Style mods and expanded the circuit to have second channel of beautiful cascaded overdrive. It is specifically designed to combat that unpleasant wooly smear that Deluxes can be known for. This design buttons up the bottom end, supercharges the amp with much more immediate note tracking, and expands upon the frequency response and dynamic range of a Deluxe platform. This amp is really something special. The Mandalorian comes in both head and combo. For the combo amplifier, speaker choice and new head cabinet will fluctuate the price.



The HyperDrive is THE faithfully and meticulously reproduced experience of one of the most beautiful cascading overdrive amplifiers in the D-style world. The voicing possibilities are as endless as there are different players. Each amplifier is designed and voiced to your needs, hands, and gear. If you happen to be familiar with the circuit or era that you need, I am versed in them all! Your hands will thank your for this one!!

Slide Winder

This amplifier shares a familiar face with a famous tweed amplifier and lives in the world of incredible "sleeper" amplifiers. It boasts a redesigned circuit that separates and then tunes each individual stage of saturation in a way that takes what we love about tweed amplifiers and gives it a breath, dimension, and depth that is stunning, while expanding upon the identity we already loved. It is a truly 3 dimensional amplifier with a famously expanded frequency response and dynamic range. Its extra stages of soft saturation gives it a feel that makes me imagine the child of a Steel String Singer and a 5F6-A amplifier. This comes loaded with a GZ34 tube rectifier and a dual 6L6 output section.



This is a beautiful and rare take on the 50 watt, 4-input tweed amplifier. This amplifier is rectified with a 5U4 tube rectifier and built with an EL34-powered output section. Although housed familiarly, this circuit has been heavily redesigned to increase frequency response, dynamic range, and generate more intentional and tuned saturation across each gain stage in a way that eliminates woof-y bottom end and maintains note distinction at higher volumes.
