Ok, here's a Crawler-in-a-HSS-strat-user for a long time.
1. No, the Crawler is not extreme hot at all. Just a tad more output than say a VHII. Balance with the neck-Irish Tour is no problem for me. The volumejump is moderate, not big.
2. Clean the Crawler sounds gorgeous, yet not whimpy. It does a reasonable Brian Setzer-imitation (add some slapback).
3. The splits are great, together with the middle-Irish Tour. Also the Crawler splitted solo is like having a telecaster under your fingertips.
4. The AV-magnet helps to cut. The topend is a little more round compared to a Mule, but there's enough treble.
5. This pickup cleans up very good.
6. It has a lot of PAF-pedigree, yet with a nice dosis extra mids. A good thing in strats.
7. Soloing above the 12th fret is a joy, cause tones stay fat and clear.
8. The Crawler has a unique growl when pushed.
9. It can do all kind of styles, but the pickup operates more on the vintageside of the spectrum. But hardrock is no problem. Tight metal is not the best feature of this pickup.
10. It's $%&#ing great on all kind of amps.
Amen
(But, the Abraxas would do too, just a bit more direction Mule, with more mids and less treble than a Mule.)
