Vintage Hiwatt DR103 Amps: Wet/Dry, Plus UA OX & Fryette Attenuators – That Pedal Show

Published on Oct 12, 2018

n this video we indulge in TWO vintage Hiwatt DR103 guitar amp heads (1972 and 1973). We begin by hearing them in a wet/dry configuration including an original Binson Echorec Baby, before moving on to (slightly) more real-world volumes using two different types of attenuator.
Hiwatt 1 is demoed using the Fryette Power Station (V1), Dan’s favourite attenuator. (Timings listed below.)
Hiwatt 2 is demoed with the Universal Audio OX Amp Top Box, a reactive load attenuator that includes speaker and mic modelling. You can hear both the real mic’d cab and virtual mics. Obviously, we include a selection of nice pedals along the way.
A note on volume. The Hiwatt DR103 is ludicrously loud, so to have two of them going at once is borderline barking mad, not to mention dangerous. We don’t get into cranking them unattenuated.
It might be confusing when Dan and I are sat there remarking how crazy loud it is… when your experience via the YouTube video is that everything is a similar volume. We explain that in the video, in terms of adjusting the mic input gains accordingly: loud amps, less mic gain. Quiet amps, more mic gain. If we left the mic gains low, the quieter, attenuated amps would sound thin and rubbish (because they're quiet in your speakers/headphones).
The point is that the physical experience in the room differs from what ends up being recorded - such an important topic when listening to gear demos online. We should never forget it!
