I have a bunch of others, but these are my go-to-guitars depending on the genre. Kinda wish I had a Tele and/or an ES-335-type 7-string. Gear lust never is satisfied.
You can find a reasonable selection of 7-string single coils. Lollar makes the Tweed, Blonde, Blackface and Specials in 7-string. BKP offers all the singles as 7-string. Duncan has the SL-1 and SL-5, plus can do more in the custom shop. That guitar, for example, as a Duncan Cool Rail in the bridge (hidden under the pickup cover).
