John Squire

John squire played a pink fender stratocaster and a Gretch(possibly a country gent) guitar during the early Roses period along with a Vox AC30 amp, to get the classic jangly tones.

In this picture you can see John Squire using a Fender Twin Reverb model known as the Silverface because of it's silver controls panel.

During The Stone Roses' 2012 reunion, John Squire used a Mesa/Boogie Lone Star Special Amp, as evidenced by images available through Google.

John Squire is seen using the Mesa/Boogie Mark III Guitar Combo 1x12 in his live setup, as detailed on Pdmcauley. The Mark III, a simul-class amp, allows switching between 15 watts in Class A mode and 75 watts using both EL34 and 6L6 tubes, providing a versatile range of sounds. Known for its darker tone compared to the Twin Reverb, the Mark III was integral to Squire's sound, offering overdriven clean tones at lower volumes. While it features a Rhythm 2 channel for overdrive, Squire primarily utilized the lead channel for his signature clean and powerful sound. This amp, no longer produced after the mid-90s, became a key component of his massive, dynamic live tone.

In 1989/90 Squire had firmly grounded his liking of mesa boogie amplification. This was a company who were arguably leading the field in valve amp technology. Squire had ditched the limitations of the twin reverbs and wanted to immerse himself in the more versatile mesa boogie tone. Having used a Mesa combo for the past few years. Squire decided to rack mount his set up with even more versatility. Mesa Boogie had released a rack pre-amp called the 'Quad'. This encompassed almost all the tones available from mesa amps. It had rhythm and lead channels of the Mark II and Mark III amps built into one.

These are the type of cabs John used along with the rack from the same period. They are half back angled cabinets which means that the bottom two speakers are sealed off by a panel but the top two are open/accessible and also that the top half of the cabinet is angled back the way. This is all to do with the type of sound produced and in what direction etc. In fact, this is actually one of John's old cabs.

In the image titled "spikecabs4.jpg," John Squire is seen using a Mesa/Boogie 2x12 Cabinet during the Spike Island sound check. The photo shows Squire's setup, which includes both 4x12 and 2x12 cabinets, with the latter positioned on his far left. This setup was likely used for significant events, possibly including Glasgow Green, suggesting a substantial investment in his live equipment.
