The "revolving door" of gear - amp edition

Continuing in the "revolving door" series, today we look at some of the guitar amps that have come & gone from the studio in relatively short time...

H&K Switchblade 50 combo
The good: infinitely versatile... like a Triaxis combo (MIDI programmable tube amp) with built-in effects (modulation + delay + reverb)
The bad: sounded buzzy/brittle/harsh, particularly when compared to the Switchblade 100 head I used to own--not sure if it's a function of the 50-watt power section or something else, though I did try swapping tubes/speakers to no avail; effects (particularly modulations) are not overly tweakable

Laney TT100H head
The good: lots of amp for the money... 3 channels with lots of voicing switches, spring reverb, footswitchable solo boost, MIDI control
The bad: kinda sterile and therefore uninspiring... sounded more like a solid-state amp than a tube amp

Marshall JMP-1 preamp
The good: 4 different Marshall-esque circuits in a single rack space MIDI-programmable preamp... kinda like a gold-plated version of the Triaxis
The bad: not overly dynamic; general consensus is that the tubes are probably more "marketing tubes" than "preamp tubes"

Mesa/Boogie Triaxis preamp
The good: 8 different Mesa circuits crammed into a single rack space MIDI-programmable preamp with 1/4" relays for switching other rack gear and stereo FX loop; endless array of LED's on the front panel look like something out of Back to the Future
The bad: again, nothing truly "bad"... not as dynamic/responsive as some of the Mesa combos I've owned, but still more warm & tubey than the JMP-1

Peavey Penta head
The good: a couple of the voicings (star, cactus) have a lot of vibe; amp is self-explanatory as it gets from a controls standpoint; retro green vinyl covering looks like an old school bus seat
The bad: the other voicings are less than inspiring, with "mudflap girl" being the worst; amp sounded a bit sterile regardless of how I tweaked it and which tubes/speakers I paired with it, perhaps because 140w is too loud for just about anything

Reason Bambino 1x12" combo
The good: kudos for being able to cram 3 footswitchable channels into a 1x12" all tube combo that can be switched between 2-8 watts
The bad: not overly tweakable... hard to dial in good tones across all 3 channels simultaneously due to the shared controls; the tone of 6AQ5 power tubes is unique (not necessarily bad)

Soldano SL-60 head
The good: forerunner to the Hot Rod series, claimed to be similar to the SLO in circuitry and tone with a lower output (less deafening) power section
The bad: it's a one-trick pony (single channel amp) with a pretty good trick... not much in the way of features/flexibility but gets the job done
