Moi? It's several pieces of gear, which I sold when I was either young ans stupid, or broke and neede the money:
1. Charvel Surfcaster - bought in late 1990, and sold in Mid 1992. Mine was the original 2 lipstick pickup model, in lollipop orange. It looked cool (so anti-superstrat, during a time when those were all the rage), was very well made, and had a killer neck (one of the best I've ever played on). It had phase switching via a push-pull switch on the tone control, and an updated Fender style (Wilkinson I think) vibrato, that stayed in tune pretty well. It was wired for humbucking with both pickups engaged. It's only weakness was its Chandler lipstick tube pickups. They were nice sounding clean pickups, but kind of underwhelming when the dirt was dished in. It was IMO, too nice of a guitar to rout out/butcher for a humbucker, so I sold it. :( It took me a few years, but I realized that I was a moron for doing so. I should have liked it for what it was, not what it wasn't. Besides, it sounded pretty gutsy (like a regular Dano), with both pickups engaged. I'd love to have another one, but they go for ridiculous prices nowadays (often over $2000).
2. 1962 Fender Tremolux amp - what a dope I was! I had this for a short time in 1990, when I was playing in a pop covers band. It sounded great - especially for dishing out vintage style dirt! But I could never crank it up in the band. With dirt pedals, it was OK, but not stellar sounding IMO, at lower volumes. It took me a few years, but I realized that I was approaching the amp in the wrong way. Nowadays, with attenuators being much more common (and much better quality than the few that were made back then), I'd love to have another one. But, unlike in the early 90s, when you could get pre-CBS Fender heads stupid cheap, nowadays, Tremolux heads are a bit on the pricey side for my tastes.
3. Fender Princeton Reverb II - another stupid mistake on my part. It was one of the Rivera redesigned amps. I bought mine in late 1989. It sounded pretty good (especially with a clean boost run into it), but I began to feel that I had to have an amp with a 12" speaker. Also, this was the time period when it was looking like 6V6s were going to become unobtanium. So, I sold it. I'd like another one, but like almost all Rivera era Fender amps, they've become collectible, and go for some serious bucks!
4. Marshall Valvestate VS100 - yes, a Vavestate! Mine was the 2x12, 100 watt combo version. I bought it from Mars Music (remember those guys?) back in 1999, when I was going through long term hard financial times, and needed a replacement for all the good amps I'd sold during the previous months. It had nice cleans (no, not in the glassy Fender Twin, or Roland JC 120 sense, but not muffled either - nice and warm), and oh so nice and slamming grind at high gain (all you had to do, was turn down the treble to 5 or so, to keep the fizz away). I had no intention of selling it in Oct. 2000, but due to my stupidity of lending a former friend (who never paid me back) a significant chunk of change, I ended up in a serious money crunch, and had to sell it, just to have enough money for next month's bills. I'd like another one, and they can be picked up pretty cheap nowadays, but those I've seen, are in pretty rough shape.
5. Gibson Howard Roberts Fusion - sold in early 1999, at the start of a long stretch of financial hard times (from 1999 - 2004). This was my main gigging axe from 1992, until I sold it. It weighed a ton (about 13 pounds as weighed [twice] on a scale). About the only genres of music it didn't sound good at were surf, and country (too dark and jazzy sounding - not enough twang factor). It had a great neck too. But I needed the money. I have yet to find one for sale that I had the funds for at the time it's for sale. Strangely though, there was an upside to the sale of this guitar. Before I sold it, I was basically a Gibson Girl, and seldom would consider any other brand of guitar for my main instrument (and if I did, it was not for long - maybe 3 or 4 months tops). Selling the Howard Roberts, forced me to consider playing other, more affordable guitars, and as a result, introduced me (via a cheapo Synchromatic Jet Club) to the world of Gretsch guitars (which I blown off years earlier, as only being good for playing oldies, or rockabilly).
