In my limited experience, a teal stripe such as yours would date from 1990 on. The Solo Series Bandit 112 was manufactured after the Bandit 75, beginning in 1988, continuing to 1995. But then again I have an old Peavey Envoy 110 teal stripe that is a 1990, and uses the serialization system of the 1980s. My Peavey Studio Pro 112 TransTube (1995 or 1996, I believe) has an 8 digit serial number without a prefix. IIRC, some time in the early 1990s, that serialization system changed. And in the lower right hand corner of the nameplate is the designation 84C, which corresponds to the year indicated in the serial number. So, for example, my Bandit 65's serial # is 4A-01900152, so my Bandit 65 was an amp manufactured in year 4 of the 1980s, i.e., 1984. And in the lower right hand corner there was a number and a letter corresponding to the year the prefix indicated. That was followed by a letter, which IIRC ('If I Recall Correctly,' in case you were wondering) indicated the type of gear in question. Thanks for the dating Ron, and Jack I appreciate your explanation of the speaker issue.The first digit of the prefix was a number, indicating what year in the decade the piece was manufactured. (This also relates to another thread that someone put a 12' speaker in a Nashville 400 and wanted to compare it to a Nashville 112, which you can't because of the overall system's tailored response). The tone mod basically restored the amp to the response it had with the 1502 speaker. Later (about 89 or 90) Peavey started using the 1501 speaker (what is currently used in the Nashville 1000) and that changed the overall response of the amp. The amp was originally designed for the 1502 speaker. However, the early Nashville 400's, with the 1502 speaker do not need the mod (but people install it anyway). More lows are added and the high end is not as 'brittle'. There is a major difference in the low end and high end with the tone mod. Peavey and John Lemay had mods but it wasn't until about September 96 that Peavey made a production engineering change and incorporated the mod component changes into production.

The difference between a 'stock' (Unmodified) 95 Nashville 400 and a late 96 is the factory tone mod. Your amps should be a 1995.here is the post: Going by what Mike Brown from Peavey said in this post a few down the page here,

Is there a way of telling the age of a Peavey Nashville 400 by the serial number? (The serial number is 5a 02376717.) I believe this is an older model, so my next question is with all the talk of the modifications that can be made to the older models, do they compare to the newer Nashville 400 amps when the modifications are made? I'm looking for suggestions on buying used or biting the bullet and going for the new amp.
