Interesting Amp Find Part 1 – The Mesa Stiletto 50W

October 22nd, 2016

mesa-shotI would normally categorize myself as a “less is more” person when it comes to amplifiers. I tend to favor rather simple amps, usually single channel, and use a couple pedals. Most of the time I’m using a Dr. Z Remedy, but also have a Bassman, a Custom Vibrolux and as of recent a Mesa F50 (the next blog topic).

But along comes this Mesa 50W Stiletto that we took in trade. I once had a 100w/50w Lone Star Combo, and it shares a lot of the options, knob assignments and tweaking possibilities. So even though I have never played a Stiletto, I somewhat knew my way around it.

This amp was Mesa’s answer to the Marshall sound, and as such sports EL-34 power tubes, a Plexi/Bassman style circuit, and a sealed cabinet with a Vintage 30 speaker. It has the Mesa “spongy” switch that drops the amp voltage for more touch response, and the ability to switch between tube and solid state rectifier (individually on each channel). Also like many Marshall amplifiers there is no reverb.

Initial impressions of the amp was that it was extremely bright and tight. On regular power and solid state rectifier, this amp as very little give, and if you’re a “spongy” amp guy like me it’s a little disconcerting. But between the tube rectifier, the spongy switch, and the three position “character” switch for each channel, there is something for everyone.

I like EL-34’s, and they have a very complex and harmonically rich top end. This helps the Stiletto pump out some awesomely good clean tones. By running on spongy with the gain and master around noon, and using the tube rectifier, it’s not hard to get some sweet touch-induced tube crunch. The amp also has an overall level control, and you can get these tones at reasonable volumes. But if you want your own personal Twin, run it on solid state rectifier and full power and you’ll have ample clean headroom. It’s likely that if you ask a typical Mesa player how they like their clean channel they’ll say, “I don’t know.” The Stiletto has a clean channel worth knowing.

The gain channel is naturally quite bright (like a Marshall) and don’t be afraid to twist the tone controls to tone it down a bit. But once you have it dialed in, it’s got some amazing Brit-crunch that has overtones and character out the wazoo. The sealed back cabinet helps to tighten up the sound, and the enclosure is not a parallel box, we assume in order to reduce standing wave forms. The total gain potential is end-of-days crazy, and we can’t imagine a usable scenario. But if you like tight, harmonic crunch you can cut with a knife, it’s freak’in awesome. You can’t model this….

Drawbacks? The Stiletto combo must weigh around 70 pounds, so it’s a good thing it has casters. Also the Vintage 30 has an inherent midrange spike, and some EL-34 tubes are likewise, and we found the standard Mesa power tubes were a bit too forward in this respect. We are using some groove tubes that we like, and if we can find some Winged C’s we’d probably be really happy. We also tried a Warehouse Reaper HP in the Mesa, as we’ve like the Reaper in the past. We could not get it out of the cabinet fast enough. Just goes to show that Mesa really does engineer the amplifier, and you can’t just stick anything in there. Same with pre-amp tubes: They are not easy to get at, and just leave the Mesa tubes in there. If you can find a NOS 5U4GB, go for it.

I sort of thought that we’d move this Mesa along as soon as it came in the shop. But it sounds awfully good, and we’ve taken it on gigs where we don’t have to haul it up stairs. On cleans it comes close to our beloved Dr. Z. Remedy, and it can break up a lower levels. If you don’t want to bring any pedals and just use the gain channel — and if you can open it up — it’s other-worldly.

The Stiletto does not really EQ or respond like your typical Mesa, and in that respect it was probably somewhat misunderstood, and underappreciated. But it’s probably our favorite Mesa so far, and highly underrated. They are out there anywhere from $800 to $1300 and represent a true bargain.
