This is the type of tuner Squire used throughout the Stone Roses. A Boss TU-12 chromatic tuner. Again another Boss product in Squire's armoury. As you will have seen by now, John always sought the best in equipment. This tuner is considered the 'industry standard', which really means it would be the first choice of many people in the field of guitar. Professional players, guitar techs, guitar repairmen etc. It is a solid reliable piece of kit and comes with a very durable plastic casing. It has a needle and lights to cater for both sides of the tuning argument. It can also be used for Bass guitars aswell. The chromatic option is essential if, like Squire, you are playing tunes with a capo. This requires you to tune to flat(b) and sharp(#) keys.
Here is a pic of the Roses playing in Sweden. If we check closely on top of the middle speaker cabinet behind Squire, we should be able to make out his tuner. Although it isn't the closest picture, it is the same as the one pictured above left. Interestingly, there is another pedal in front of Squire which could also be a tuner. It looks very much like a boss pedal. These floor tuners have become very popular in recent years, especially the boss ones. The price of these will keep going up as they can't make them fast enough to meet the demand in this country. Probably about £80 at the moment.
The TU-12 tuners have jumped up in price over recent years. You would probably be looking at about £80-£100 for this tuner today. I would say it is a bit overpriced. A second hand one would be a good bet for about £40-50. But not many people are keen to sell them. So that should tell you how good they are.
