## Description

BOSS TU-3 Chromatic Stompbox Tuner pedal : desertcart.co.uk: Sports & Outdoors

Review: Sensational Secret Sauce pedal!! - The BP-1W is one of the jewels in the Waza Craft crown. Boss outdid themselves with this low key gem-it’s part boost, part drive, part compressor and all brilliant. I use this primarily for solo shows with my Fender American Acoustasonic Jazzmaster, it’s up front on a pretty extensive board (behind a TU-3W and a ten band EQ), and I use it as a clean boost for fingerstyle, to push my overdrive for solos, to stack with my compressor for edgy tones and controlled feedback and sometimes just as a mild drive. The Nat setting offers a slightly hairy and vaguely compressed clean boost, like an MXR Micro Amp into a Diamond Comp turned way down, but more hi-fi. It simply makes everything sound better and bigger. RE mode is a little darker and crunchier, bringing a replica of the Space Echo pre into play. The CE mode sounds just like a MIJ CE-2 with the chorus controls turned all the way down. The CE mode is why I bought this pedal-my producer has an early ‘80s CE-2 which we often use as an always-on “bettering” pedal, such is the great tone of the preamp in it. This does the same job but for way less money than an MIJ CE-2! The BP-1W is super easy to use. Two knobs, one three way switch, and an on/off treadle. Great tone is easy to find-just switch it on, find unison output, add gain to taste and let it do its work. It just works so well. Would probably be my desert island pedal. I bought one before, didn’t appreciate the subtlety, returned it and almost immediately bought it again. It’s simply sensational.
Review: I have a TS-9 as well, but I prefer this! BOSS is BOSS! - This new, Waza Craft, in other words; Made In Japan Super Overdrive (as were the OG BOSS pedals), is superb! I have a fair few overdrives, and although the Waza Blues Driver (BD-2w) is probably my favorite for lead boosting as an overdrive, this one isn't far behind, and is arguably the better 'always on' pedal of the two, especially for Hard Rock / Heavy Metal tones! That's probably a biased statement, as that's the genre of music I prefer, but stack the two together and you've got something quite special! Harmonics just seem to jump out with this pedal on, and I find myself having a very handy 'Van Halen-esque' tone constantly and easily - great for lead and rhythm. Simple, foolproof layout and knob options, typical bombproof BOSS build quality, low current draw (15mA for all you pedalboard builders out there!), comes with a 9V battery as well. The switch in the middle changes the character of the drive from the old, standard SD-1 (but with improved circuitry) to a more modern take - both are great, but I personally REALLY like the Custom option! Nothing to dislike here, superb pedal at a more than fair price.

## Questions & Answers

**Q: can this tune a saxophone??**
A: Saxophones absolutely need to be tuned every time you take off the mouth piece or with temperature changes such as going from indoors to outdoors on a cold night (marching band).  Tuning is done by shortening or lengthening the distance an the neck of the sax by moving the mouthpiece in or out.  This tuner could be used to tune a saxophone if you have a cheap mic that has a 1/4".  That said there are less expensive tuners with built in mics that would better suit your purpose.  

Please note though that no matter what tuner you buy, if it is set to concert pitch (440Hz A / piano tuning) you will want to transpose the notes from Bb (tenor) or Eb (alto) to concert pitch when tuning your saxophone.  In other words when you play a C on a tenor saxophone it is a Bb in concert pitch.  For alto a C is an Eb in concert pitch.  There are some very expensive turners that you can change the tuning from concert pitch to other pitches but they are a waste of money since transposing is not difficult.  Make a chart or download one if you struggle at first.  Remember that your sax could be sharp on some notes and flat on others so check multiple notes and find the tuning where the most notes are in tune and those that are not are just a little sharp or a little flat.

**Q: How does the TU-3 effect a fuzz face if it's placed a couple pedals away after the fuzz ? I assume it has a buffer like most Boss pedals.**
A: It is buffered, but the buffer won't affect anything that comes before it. Since certain fuzzes don't "like" buffers, putting those before the tuner will work fine.

Guitar > Fuzz Face > Tuner ( or any buffered pedal) > Amp

**Q: Is this product adequte for a 10 string  pedal steel guitar ? I was told to get a tuner that shows the frequency and I do not see a # on the  display**
A: This won't show the frequency in Hertz, but it will indicate pitch, and the 10 string pedal steel should be in its range. There is a dot on the display to indicate a sharp.

**Q: Will this work when only plugging the input?**
A: Yes

### ⭐⭐⭐⭐⭐ Probably the best pedal of it's type
*by A***B on 24 February 2025*

Likely the best overdrive. It has a really good range from subtle to slightly over the top. Really nice when playing monophonic or duophonic. Not really for metal, there are better distortion pedals for that I would say, but great for rock and blues style for many popular bands styles. Not sure I needed the waza features, when on, the waza reminds me of the Dolby switch hifi devices used to have ie it adds tone maybe a little dull and less rough. Through a large amp this may make a huge difference. Better to have it and not regret it later though when you see reviews or your friends tell you how great waza is
