Acorn Amplifiers Solid State Preamplifier review – the ‘Peavey in a box’ you didn’t know you needed?

The clip is easy to find on YouTube – just search for “Josh Homme’s secret weapon”. The Queens of the Stone Age frontman goes off to find the amplifier, a crappy little 1980 Peavey Decade practice combo, then pops it up on his lap and tells the interviewer: “This thing is incredible.”

That was enough to prompt Peavey to create a signature reissue of the amp itself, as well as including a Decade model in the line of pedals it put out last year. And it also prompted Atlanta builder Acorn Amplifiers to give this 10W titan the proper boutique stompbox treatment – in the shape of the Solid State Preamplifier.

Acorn Amplifiers Solid State Preamplifier – what is it?
Strictly speaking, this isn’t a Peavey in a box – it’s a Peavey in a box in a box. Because the SSP is a compact version of the Acorn Solid State, a bigger pedal that includes a recreation of the Decade’s output stage and can be plugged straight into a speaker cab. The preamp-only model might not be able to do that but it keeps all the core features – three-band EQ, footswitchable ‘normal’ and ‘saturated’ channels, pre and post gain controls – and adds a toggle switch marked ‘thick’ for a chunkier tone option.
The main drawback of the downsizing process seems to have been in reducing the gap between the two footswitches. Hitting one and not the other on an empty floor can be tricky; in the middle of a packed pedalboard, it’ll surely be like trying to perform brain surgery with barbecue tongs.
One design feature I do like is the light-up Acorn logo, which turns from cheery green to fiendish red when you engage the saturated channel (and is extra-bright when running off 18 volts). Pity there’s no way of telling which channel is selected when the pedal’s in bypass, though – you just have to remember how you left it.

Acorn Amplifiers Solid State Preamplifier – what does it sound like?
Deliberate spoiler for anyone who just wants to know if it sounds like Songs For The Deaf: yes, in the right setup, it absolutely does. But between the channel footswitch and the toggle, there are four very different sound zones to explore here and that’s just one of them.
The normal channel goes from clean to medium-scuzzy, adding a crisp edge to the top end and some decidedly solid-state firmness to the bottom. This could certainly serve as an always-on tone improver for some players. The firmness doesn’t last long when you flip the switch down, however: now you get a more wiry kind of crunch that flirts with horribleness at times but mostly keeps things nicely clear and ultra-sparkly.
Switch to the saturated channel and the first thing you might notice is a fractional difference in output level – up or down, depending on where the pre gain is set and whether you’re using 9v or 18v. Sadly, there are no individual volume controls to correct that; happily, this channel is a monster. The effects of the toggle seem to be magnified here: the thin mode is beautifully abrasive, in stark contrast to the chunky richness – albeit still edgy – of the thick setting.
In both cases it really does sound just like the dirty channel of a small transistor amp from the 80s: raw and insolent in the best way imaginable. It’ll even do the old doomy scoop if you kill the thickness, set the mids to zero and max out the gain.

Acorn Amplifiers Solid State Preamplifier – should I buy it?
The sound of this pedal is hard, dry, unrefined – all the things that some of us longed to escape from when a little practice amp was all we had. But that stuff has a vibe of its own, and a usefulness beyond mere nostalgia, especially when it’s presented in such a smart and multifaceted package.
Practical issues might limit its appeal for live work, but maybe it’s fitting that the SSP’s real strength should lie behind the scenes as a recording tool – just like Josh’s old Peavey.

Acorn Amplifiers Solid State Preamplifier alternatives
It’s made in Taiwan, but the Peavey Decade Preamp ($199/£179) does have the right name – in the classic spiky font – on the front. More interested in the Josh Homme connection? The Stone Deaf PDF-2 (£160) is the latest version of a drive and EQ pedal he actually uses, while the Funny Little Boxes Skeleton Key (£99) is a ‘dirty boost’ inspired by the sounds of QOTSA.
PS. Thanks to Joe’s Pedals, Acorn’s UK dealer, for the loan of the SSP.
