Dig the excellent tequila-sunrise comin’ on behind the Altec Musical Instrument Speakers. It was a popular, if pricey, move in the 70s to replace the factory-installed drivers in your Fender Amp with an Altec (or JBL) aftermarket speaker. Many amplifier manufacturers of the era offered these as factory-installed options as well. I have never liked the sound of of these speakers in a guitar amp. It’s likely simply because I have a more roots-oriented guitar style, but i find that Altec and JBL speakers really rob a good tube amp of the responsiveness (touch-sensitivity) and proper harmonic-breakup that I depend on from the amp. Maybe if you are into Jazz and/or Metal these would be a good choice. Anyhow, I always replace them with regular Alnico or ceramic instrument speakers, which generally have a more limited frequency response. Another downside of the JBL replacement speakers in particular is that they weigh a goddman ton, turining your Deluxe Reverb into something requiring casters.
Since this is essentially a live-sound catalog, the microphones on offer are limited to a range of 5 hand-held type units. The top-of-the-line dynamic on offer is the 654A. I bought pile of 4 of these on eBay a few years ago when I needed some mics for a series of rehearsals we were doing. They were pretty cheap and I figured they would work pretty well. I found them to be not especially durable, but decently so. They have pretty good sound, but the feedback rejection is really really bad, even with properly-positioned monitor wedges; but perhaps their worst feature is that the shafts are so frikkin thin that you need to use those awful spring-loaded mic clips. We still use these in the rehearsal studio when absolutely necessary, but I cannot recommend them. Might sound cool on acoustic guitar for recording applications.
