The PSA-1 is a 1U rack device that uses analog modelling to simulate the sounds of classic amps. Effectively you can set separate distortion levels for low, mid, and high frequencies. It comes loaded with 49 presets covering various Marshall, Fender and Boogie amps as well as bass amps. The signal path is 100% analog, but you can save settings to one of 49 user memory locations. The programs can be accessed form Up/Down buttons on the front panel, or by MIDI program change.
The Tech 21 'character' pedals use the same sort of technology but with some of the parameters pre-set to suit the kind of amp they are mimicking. Here you have the full range of tweakability.
The PSA-1 can be considered a pre-amp or an amp simulator, but it doesn't have any onboard speaker simulation as such. It can be used into a clean guitar or bass amp, or into a power amp with a suitable guitar or bass cab. For direct recording most of the (dirtier) sounds also require a cab simulator device, IR loader or similar. Even so, I recorded the clean guitar in this clip without a cab sim.
To me, the standout guitar presets are 07 (Hendrix - Marshall), 12 (Stevie Ray - Fender) and 48 (AC30 Queen). There are also a number of bass presets including SVT and Bassman. As is usually the case with presets, you probably won't like them all, so copy one you like to an empty memory slot and tweak away.
There are plenty of connectivity options including front and rear inputs, FX loop, balanced outs, and MIDI in/out.
The unit is in full working order. The only negatives I can find are:
(1) The Up/Down buttons sometimes jump more than one increment at a time (but it's easy enough to go back to where you want to be);
(2) Some of the lettering has worn away on the rear panel;
(3) The mains lead is quite short, but it is terminated with an IEC inlet, so just plug in a kettle lead of suitable length.
I don't have a hard copy manual but you can download it here.
Reason for sale: I have used this much less since getting a Revival Drive!
Price includes insured UK mainland delivery. Not really looking for trades unless you have an Alesis Control Pad to offload.
Here's a dude showing off some of the guitar presets:
I got this off here last year IIR. Used it once and decided i prefer the BDDIv2 tone (plus i was using a Stomp anyway).
Works well, but slot one footswitch sometimes needs two presses. Might be user error but its not as fast sometimes as the other two foot switches. This is how it came to me.
Other than that, works perfectly. Might have the box, manual etc, but if not it will be packed well. These things are built like tanks anyway.
Price includes UK 1st class post.

This is a simple and easy to use pre amp pedal/DI box for live and studio use. Standard 3 band EQ with mid sweep. Great to add some extra life to an old passive bass or compliment your amp.
I have gigged it a few times but it is in great condition and comes with the original packaging, instructions and I can do shipping, too.
Now sold: DSM Noisemaker OmniCabSim Deluxe for sale, fantastic little box of tricks - it's a cab sim, plus DI pedal, plus headphone amp, perfect for home recording or if you're playing live using in ears and DI'ing to front of house. The top three knobs allow you to dial in the response of the speaker cabinet you're after, crafting the top end response, the low end roll off, and the intensity of the natural resonant frequency of different size cabs; you've then got two knobs to adjust the mid response, adjusting the amount of mid-scoop at 450Hz and adding punch with a boost at 800Hz to cut through the mix. It's great to be able to dial in the exact sound you want, and then have the ability to make fine tune adjustments to suit each room you're playing in.
The built in DI means you can send the affected signal to front of house via XLR or 1/4" jack, so the sound you setup at home is the sound that the audience hears, and a 'through' output so that you can send an unaffected signal to your amp
It's also got a headphone amp built in, so you can also use it as a personal monitor setup with in ears, with a separate Aux in jack so you can feed your monitor mix in too. All this is a fantastic form factor - the same height as a boss pedal, and about 1 and a third times the width.
Boxed and in great condition - now £180 including UK delivery.
Up is my recently serviced Sansamp Programmable Bass Driver DI. 3 Programmable channels of the very best Sansamp-y ness. Perfect for being stuck at home recording and as a live tool when gigs happen again. Runs on 9V, Battery or Phantom Power for ease. It sounds like a Sansamp Overall condition is quite good, and as I say recently serviced so sounding and behaving like new.
