The Tweed Recording Pro is Carl’s take on a Tweed Champ-style circuit, expanded with additional versatility. In addition to having a 12" speaker, it features power scaling controls that allow you to dial in a wide range of tones and volumes. Here’s what their website has to say about it:
"The Tweed Recording Pro is as classic sounding as it is innovative. Countless recordings have been made with Tweed amps and they simply sound wonderful. Gritty, warm, and lively are all good adjectives for the sound. However even the smaller Tweed amps can be too loud for a small room or long tracking sessions. The Tweed Recording Pro solves this issue because it has on board London Power Scaling allows for power from 10W down to a whisper quiet 1/10W! Now you can have cranked Tweed tones at any volume. This all done very transparently with no change in tone over most of the volume range. The feature can be fully bypassed when not needed.
The Tweed Recording Pro to has ultra-low floor noise and has practically no hum or hiss making perfect for critical recording or pedal use. Adding to the tonal variety the amp can use any 6L6 type tube, a 5881s, or 6V6 as power tube so you can tailor the tone. The amp comes with 12" that speaker gives you wide dynamics, powerful overdrive, plenty of cleans and great fullness to the sound. It's simply amazing!"
