Wallace BKW45 test

Wallace BKW45 Amplifier head

There's a small claim on the Wallaceamps.com site about the BKW45 that says:

"This amp will cover all the sounds from the 60's to the 70's."

Not that I had any doubts, but I decided to put the claim to the test, just to see how far I could get with just one amplifier.

I put original recordings of well-known artists collapsed to mono in the left channel, and tried to duplicate certain instruments in the right channel using only the BKW45 into a Marshall 1960BX as amplification. The goal of this experiment was to spend as little effort as possible in replicating the tone of the original records.

For each part, I attempted to not spend more than 30 minutes figuring out the part, dialing in the tone and recording the track. At this pace, there are some performance mistakes, but the goal was tone more than note-for-note left-to-right accuracy. The measure of success when replicating the tone is the right channel should create a convincing stereo image of the left channel, with regard to the amplified instruments.

To assist in the rapid pace of dialing in tone, I maintained 5 different microphones (U87, C414, MD421, SM57, e609) active at all times on the Marshall 1960BX cabinet and simply chose the microphone track that most closely matched the original recording. In a few cases, it was necessary to add small amounts of either compression, eq or reverb in order to properly match the left channel. The bass tracks, where applicable, were also performed through the exact same BKW45/1960BX and microphone setup.

These are all edits of the songs, roughly 1-2 minutes each. Simply pan to the right to hear more of the BKW45 tracks. (Note: these are 192kbps MP3s and suffer some quality loss compared to the actual recordings.)

There's a few 'mandatory' artists still missing that I hope to add; e.g. Van Halen, Stevie Ray Vaughan, etc.
but based on this experience I have no doubt the BKW45 can replicate those sounds also.

Considering my tracks were done in a small studio, in under 30 minutes each and only allowing 1-2 takes each, and performed on different instruments and different equipment than the original recordings, and considering I was trying to match tracks that were recorded by legendary artists in the world's top studios like Abbey Road, The Record Plant and Ocean Way, and considering the tracks being matched were already produced, mastered and remastered; despite all this I was very impressed just how easy it was to replicate (with reasonable fidelity) the tone of some of the most famous albums of the last 40 years using only the BKW45 amplifier and a Marshall 1960BX "Greenback" cabinet.

I think the BKW45 lived up to the claim, and then some.
