Good luck. I talked to Goodrich one time and they told me no one could get one because they didn't want anyone to build copies (valid concern). Ollie told me that himself.

That has been Goodrich's policy ever since I can remember. I had a Matchbox and the part numbers were removed from the IC. Same with my MatchBro, part numbers are gone and I think some of the transistors too.
Couldn't reverse engineer it if I wanted. |

| That is a shame, because they do not even repair them anymore. When I checked on repairs for a Matchbox 7A a while back they told me they had no one able to repair them since their dad had passed away. I was able to repair it myself, it was a tedious job, though. Luckily the part numbers were on the transistors I had to replace |

| Ken, This same thing happened to me with my Evans fet500lv.If you remember me talking to you about it some time back. It had a bad fet. I called Scott and he was unable supply me with the part. I had the number on the transistor but the prefix didn't jive. I kept digging and finally stumbled on the part I needed. I can't recall now but I think I saved the invoice If anyone needs to know where to get the FET's for a fet500lv I will try to dig up the invoice from where I bought them. There are 4 or 5 of them in the fet500. By the way the amp sounds as good as it ever did. I'm glad I didn't just give up on it. |

Goodrich is no help on this for sure. |
Check with Buddy Emmons, as he had to
do with the concept and r&d of this unit.

Ken, if you ever get one, install a "Power On/Off" switch on it. Typical of a lot of their equipment, plugging a guitar cord into the input powers it on. I put a toggle switch in series with the power lead that goes to the input jack - both the guitar cord must be plugged in and the switch in the On position for it to be powered on. Either the swtich off or no plug and the unit is powered off. I've done several of this mod to (original model) MatchBros.
The sad part is the MatchBro is the best/most authentic electronic dobro simulator (I've fooled Bluegrass pickers). But, Goodrich priced it out of the market and thus very few sales. $695.00 for the SuperBro (what I saw as the list price on one site) is a bit much, even for the limited production/market.
I have one of the original models (with the tone control in bypass) that I bought at St Louis. It was $245, ISGC special price, and back then $245 was high. |

| Greed priced it out of the market. Not a handfull of parts in there. Just overpriced and a fine example of getting what the market will bear. If we priced amps like that they would be in the $20,000.00 range. |

Jack,
The 7a comes with the switch.
I have a 6a that I put the switch on it. |

Like the Bo-Bro that Seymore sells. It is a Boss Ge7 EQ. You can get them new for a little over $100, and set the sliders. He charged $250 for them (I know, that's what I paid). I know some who have used $25 Behringer and $30 Danelectro 7 band EQ's and got the same effect. As steel guitar players, we tend to be swayed into paying absurd prices for items because "they are made for the steel guitar". But since we pay what is asked without any question as to why it is so much (think Telonics volume pedal at $500), this overpricing will continue.

Yes they are expensive. I too bought mine directly from the Big E at ISGC the first year they were out. I too modified it with an on/off switch. I too discovered that all the IC's had been scrubbed clean. Fortunately I've never had any trouble with it and I've used it a LOT! I do have a good program in my Profex that simulates really well but I don't always use/have my Profex with me. Some gigs just call for less stuff. To bad it's not in production by somebody. It is a wonderful unit. If anyone does run across the schematic I would definitely be interested in a copy. Just in case! Thanks guys, God Bless, Whip

Ken - Do you have one to open up and look at? You are welcome to borrow mine, if you want.

Well, with Bob IDing the active parts for us, it shouldn't be too hard to draw up the schematic. I'd do it for everyone, but I don't have a MatchBro, or a SuperBro.
BTW, thanks, Bob, for the semiconductor info.

I opened one the other day and fixed a cold solder joint. He was told it was "unrepairable" by Goodrich.
I really have no interest in drawing schematics for one myself. It would be nice for those that have them to have a schematic to aid in getting them repaired. |

There were four different versions of the MatchBro that I know of. Which one is the parts that are ID'd for? They probably used the same parts or at least some of the same parts in each one.
There was the Original model and the Original model with a tone control (basically a matchbox) in bypass. A MatchBro II (one that was not adjustable) and finally the SuperBro. |
