Review : YOMI from Frost Giant Electronics
Treble Boosters. You hear about these critters. You hear that if you like Brian May or Tony Iommi or Rory Gallagher or Ritchie Blackmore or Eric Clapton, you MUST have one.
Sure you can go online and search for an original Dallas Rangemaster for hundreds of dollars. Or you can get a new build of one from The British Pedal Company and my buddy Charles at electricmojoguitars.com. Or you could do what I did and take the advice of my friend Chris Spano at The Arts Music Store and hunt yourself down a YOMI from Frost Giant Electronics.
Chris told me about the YOMI when he asked that I do a review of The Mountain. I had been asking about fuzz and while there are folks who say that The Mountain, which is based on the ProCo RAT is not a fuzz, Dan Steinhardt over at That Pedal Show says that it is a fuzz. Be that as it may, Chris mentioned that Frost Giant did their own treble booster and that he grabbed the only one that came through the door and it never saw space on the retail counter. I checked and not only were there none in stock, the unit did not appear on the website. I went over to Frost Giant and their site said out of stock. Ru ro Shaggy. Over to Reverb and I found that the nice people at Axe and You Shall Receive (cool name huh?) in Brantford Ontario had two in stock.
Mine arrived quickly and while the version on the Frost Giant web site is black on light blue, I was fortunate to get one of the limited edition red on gold models as seen in the top image.
Documentation is like most Frost Giant Electronics products, meaning that it is non-existent. The YOMI has a knob marked Boost, an on/off stomp switch and a three way toggle that offers three different EQ options.
I was already set up for independent pedal tests with my silver Marshall 2550 into a silver 4x12. I had configured the clean channel to be super clean, even with hot pickups, and the ultra gain channel to sound like an overdriven Marshall, with Marshall style harmonic distortion but not fuzzy. I had the simple Marshall channel switcher on the floor and the YOMI on a stool in front of me to simplify tweaking. I ran direct from the guitar into the brand new Peterson StroboStomp tuner (review is coming on it), then to the YOMI and to the Marshall. The TC Electronics G Major that lives in the effects loop was completely bypassed. I checked the tone with an without the tuner and could hear no difference. All cables were Ernie Balls. About as generic as possible.
The first guitar that I used was my old Explorer. It's not a Korina body (sob) but it is solid mahogany and has nice heft. Like my Flying V, I find the factory pickups are a bit hotter than those in my Les Pauls and thought, hey why not. The Explorer sounds lovely clean, much as you would expect. Kicking in the YOMI in the clean channel and adjusting the boost brings a really nice bright distortion. Clicking through the three EQ settings you work with a three different levels of bass cut. I liked the top setting best which had the least cut. Definitely very playable and nice rich distortion. Wrong pickups for the Queen sound. Kick in the Marshall ultra gain channel without the YOMI and ah yes, there is Mr. Marshall. But add the YOMI and WOW! There's the sustain for days that was missing and while it sounds initially like you have lost some low end, I realized that I was getting a much more open top end than without the YOMI and pleasant feedback was readily available.
I love the sound. I will try a noise gate between the YOMI and the amp when I get around to it to isolate some of the other guitar noises when I am in glorius feedback territory, but I am not suggesting that this is necessary. You do want to play loud, which sounds wonderful but probably not your best choice at 2 in the morning. I was lighting things up between 4pm and 6pm so if I was annoying the neighbours, they had the good grace not to say anything.
I next moved on to my SG. It's a cherry model in the '63 style, albeit this '63 model as advertised from Gibson came from the time when Gibson couldn't remember that real '63s had the small headstock. So it has the large headstock. It's also got relatively low output humbuckers and while I have had it a long time, it's not a guitar that I go to very often. I had tried it with the Frost Giant SOMA (different review) and hated the sound. With the YOMI set to the top EQ and boost around 1 o'clock in the ultra gain channel it was quite nice. Not as quick to go to feedback as the Explorer but I expected that. Still going to change those pickups and I suspect that at the time, Gibson was using gum wrappers for caps and toilet roll for pots. There's no such thing as a vintage Gibson from the 70's or 80's that did not come out of the Custom Shop. But I digress...
Third guitar for the test was my red Suhr Strat, or as it is correctly known, the Suhr Standard Plus. This is a SSH configuration using Suhr's proven SSCII hum cancellation circuit. Mine is a rich red, a colour no longer listed. Which is good for me because it's freaking lovely. I love Suhr guitars, they are just so perfect right out of the box. I have this one and a custom shop Modern that my friend Andrew Lai down at Cosmo Music got built for me about ten years ago. Anyhow, the Suhr sounds great on its own, and although it is a humbucker in the bridge position, does not get all thickened up. I found it a bit too bright with the YOMI into the clean channel, but into the ultra gain channel on the Marshall with the Boost backed off and the EQ switch in the middle position it was really singing with any of the pickup configurations. I have found some pedals only work well with humbuckers while others only work well with single coils. Good to know that the YOMI handles single coils very well.
Obviously there is a lot more to do with the pedal. I want to put it into the pedal rig for my AC30 and try pushing P90s or P100s through it or one of the PRS guitars with the coils tapped. I've got a couple of very old CE bolt neck models that have the old five way rotary switch that sound awesome.
I had seen Mick and Dan on That Pedal Show covering treble boosters and while they did not cover the YOMI, I thought it was interesting that Mick concluded that if you run into a Marshall stack, a treble booster should be on your board. Brian May uses the Red Special into AC30s, and Tony Iommi played SGs into Laneys. BTW did you know that Mr. Laney was in a band before building amps? It was called the Band of Joy and included two other fellows who became rather famous, a Mr. Robert Plant and a Mr. John Bonham.
Thanks for reading and until next time, play on!
