Hi duncjam
Have you looked inside, to see which two variations you have?
And is the text colour different as well?
Regards Dr. Bob  |

I don't have my old early 90's one anymore. I removed the base from my current (stock) MT-2 (built July 2006) but the circuit board doesn't seem to want to come out of the pedal.
I've never opened an MT-2 before so I don't want to force anything - other than removing the base via the 4 screws, is there anything else I should be doing to free the board?
It has the more red-ish coloured logo text, btw. |

I have two different MT-2's, and have A/B'd them.
I bought my first one in the early 90's, serial DE38715 (Oct '92). Recently bought another one second hand as a gift for a friend, and decided to see if they sounded the same. The second one is serial OU87644 (July 2006).
BIG difference to my ears! In comparison, the old one sounded thin and lifeless, and the newer one sounded big and full, with better basss response. So, the old one went to the cupboard, and I kept the newer one for myself! I did purchase another one for my friend, which was also a late model one, which sounded identical to my newer one.
I, too, noticed the different colours of the writing, and the enclosures themselves are also slightly different colours, but that would be very hard to pick up in a photo.
I'm thinking the older one is a prime candidate for some form of modding.... |

I don't consider it shameless, Laurie! The more info and options people put forward, the better, in my opinion!
I checked your website, and I like the way you have done your instructions, so you can choose which mods you do for which result.
What I don't understand is why people recommend changing electrolytic capacitors (which are polarised) with metal film capacitors, which are not polarised. I'm am also scratching my head over this issue in another thread....http://www.bossarea.com/forum/topic.asp?whichpage=1&TOPIC_ID=8075#68318

It is easy to imagine all capacitors as "perfect" ... i.e. only providing capacitance to the exact value on the can.
A "real" capacitor is a complex beast which has capacitance, resistance, and inductance. And for electrolytics there is polarity.
Each different type of physical construction has slightly different values for these characteristics.
Ceramic construction is generally better for high frequencies and they are not used, for example, as the input capictor for a pedal because they don't pass low frequencies that nicely.
Metallised polyester is good for "mid value" capacitors - in the 0.001 to 1uF range. They pass audio frequencies quite well.
Electrolytics are generally high values (10uF up) and some say they are "questionable" tone-wise at audio frequencies. Certainly they have slightly different tonality to Metallised polyester.
And there are many other types of capacitor.
So, why change the electros to metallised poly? With great respect to Boss and many other manufacturers, electros are used because they are cheap (and for no other reason).
Some think metallised poly sounds better because they are better built (more expensive), and there is a big following for that thinking.
In reality, it can be REALLY hard to tell the difference. So much gets muddied by the expectations of the listener. I did an A-B on one of my MT-2 pedals and while there was a tiny difference neither capacitor was "better" to my ear. but then I've often admitted I'm more of a techie than a player so maybe I just can't hear it... |

I don't see a lot of difference in color between the 2 pedals I have, but the lettering on the newer one is clearer. And the rubber pad that you step on is different. On the newer one, the Boss logo is slightly smaller & the logo & letters are closer to the top edge of the pad.
The older pedal is on the left:
