Quick Overview

The Custom BL20D and BL40D are our own take on a vintage, clean, single channel tube amplifier. It’s sound is an amalgamation of the best of classic British cleans. It’s warm and fat yet bright, clear, dynamic and articulate with very well balanced harmonics.

The Custom D series amplifiers use 2 x 12ax7 and 1 x 12at7 tubes in the preamp and el84 power tubes. The 12at7 works in a phase inversion circuit which provides a substantial increase in clean headroom. Our 40w is comparable to 80w-100w from other leading manufacturers in regards to strong clean headroom.

This series of amps can be pushed into natural overdrive but only at extreme volumes. However they take effects pedals very well through the input and sound fantastic when being pushed over the edge with an overdrive or distortion pedal.

Using the high/low gain inputs, along with their highly responsive 3 band EQ, volume and presence controls many different clean sounds can be dialed in with ease.

All of the Baroni Lab amplifiers are hand built by a small team of in House engineers using only the best quality components from around the world. We use oversized power transformers, exceptionally good filter stages and Ugo Baroni’s specially developed optical switching system to produce amps with buckets of headroom and extremely low noise operation.

Every amplifier we make has individual bias adjustment for each power tube, so there’s no need for buying matched pairs and it’s easy to dial in. Feel free to mix and match different kinds of tubes.

All of our amps come complete with a variable level, buffered, serial effects loop for full integration with effects pedals and processors.

Customer Reviews

A Great Overall Amp Review by Jeff Stewart
This amp has a very distinct sound; it has plenty of headroom, so it keeps clean and doesn't colour my effects chain, and the tone is really crisp and clean. Every note is a pleasure to hear and every chord is a wall of lush harmonics. I have tried it with a number of different speaker cabs so far, and the amp makes everything sound great. Really brings life to my effects rig, and responds well to my playing style. (Posted on 10/13/2014)
