ENO Music PT-21 Guitar Tuner

What is it?
ENO Music PT-21 Guitar Tuner, made in china 2013.

I wanted to try something tiny as a tuner for my personal pedal board. The price was one factor. I didn’t want to get another TC Electronic tuner as the old Polytune i have works reasonably well and i’m familiar with the use. Recently i’ve noted that i rarely use the polyphonic mode, so i was pretty interested in these new chinese mini pedals. First i tried it out. Works. Feels responsive.. A/B’d this with my old war horse, Boss TU-2. That Boss is the tuner i use at home for everything from re-stringing to fine tuning the intonation. TU-2 is good, responsive (sometimes too responsive) and very accurate tuner. This ENO is about as fast as TU-2, doesn’t go mad and doesn’t get mixed up in frequencies.


Opening the unit up shows pretty neat work. Everything has its place (ok, the couple red wires could have been replaced by better engineering). The rubber band making the DC jack fit perfectly made me smile. Simple solution, yet quite elegant. At this point i’m not getting deeper about how it works as it is digital design. Maybe i’ll revisit all the stub articles about digital stuff one day..


It seems like the ENO PT-21 is solid and well made tiny tuner pedal. I’m yet to test it on my own board, so we’ll see how it takes some real action – handling the temperature changes and if the frequencies stay accurate on real situation. For home use this cheap little thing seems to be a good choice.

Placed it on my board and used it for a few days. Even though it seemed to be as accurate as TU-2 in the first run, the Floyd Rosed Strat didn’t agree. It does get close, but not close enough. Sad. Sad indeed.

How does it sound?
It doesn’t. But it isn’t supposed to. It is true bypass though. But for the usage.. It’s not the worst tuner i’ve had by a long shot, but it simply isn’t accurate enough for me. Not bad, but i might sell it off rather than trusting it. Oh well. Guess i’ll just need to get that Polytune mini. On the bright side, this is definitely better than DOD FX12 Tuna.

Monkee Music Satan Distortion

What is it?
Monkee Music Satan Distortion, made in japan in 1989.

Ok. It has super cool font saying “Satan” on it. It is made of plastic and it is apparently japanese 1:1 clone of  Rocktek DIR-1 Distortion. When i say it’s made of plastic, i do mean that. Even that the outer shell is made of cheapest materials possible, the insides are not that bad. There are couple other pros in it too.


The board mounted jacks are held in palce with plastic holders, not completely unlike the older Yamaha box jack’s pull relief solution.  Which in my opinion is a nice method. This keeps the strongest pull/strain away from the jacks. As some of you may know, the plastic on plastic is better than metal on plastic. Traces have that japanese  clang to them and the soldering is solid and professional looking.


Components, excluding the momentary bypass switch seem to be all good. Even the switch doesn’t have any issues, but i do believe this unit has not seen much use in its existance. As the unit is 1:1 with Rocktek DIR-1 Distortion, there is a traced schematic up at Freestompboxes forum. Although you need to be logged in to see it.


The main driver is 6458D, which is old Sanyo chip with some similarities to JRC4558. Sanyo model however is quite more high-end audio product. The datasheet is available online. I’m tagging this as “Other Brands”, as this unit is apparently only Monkee Music brand box ever manufactured.

How does it sound?
I’ve heard this type of distortions before. Below unity and basically just one tone you can get out of it. It’s not that bad of a distortion, but all the controls are pretty much unnesessary. You’ll need to have everything maxed to have a reasonable result out of  this box.  It’s that classic 80’s/90’s distortion sound that everyone is familiar. Relatively high gain. The lower than unity output level is the worst culprit in addition to weak plastic enclosure. Prime suspect for modding and /or rehousing. But for that – i’d suggest to get Rocktek DIR-01 as this Satan Distortion seems to be quite rare specimen.
