Hi there, are you tired about discussing different speakermodels for the Flextone III amps ? So let me tell you how to get a much more brillant and crisp sound from your Flextone3 in three easy steps without a speaker change. After unplugging the mains cord and disconnecting the speaker cables remove the Amp Chassis with the 4 large screws on top and the 4 small screws for the handle. 1) For those who wonÂ´t solder on SMD devices but are aware of tubeamp modifications : Solder 2 pcs of 4,7nF film cap across the In- and the Output pins ( bottomview right and middle) on both of the stacked stereo Mastervolume Pot (B 10k) , like the "bypass" caps for higher frequencies on Volume Pots in guitars or in valve amps. Seen from above on the back : these are the right and the middle pins of the double pot ! So you will have much more over all brillance and treble also at lower power settings without changing the speaker. Check first with a Clean amp modell like the DOUBLE VERB with its 2x12 emulation. If you ever have tried such an analog beast you will find it now -with the same attitude - here in the Flextone3. And all at neutral 12 oÂ´clock settings on the EQ pots. After that try chrunch and High Gain emulations. 2) For those who will try additional mods : Remove the very very small capacitor signed as "C4" from the board with a small solder pen ! If you are not aware in soldering on SMD devices please take care and better take the board to the next electronic technician or to a radio shop with educated personell. Its all at your own risc !!! These small capacitor( 47pf ) works together with the L1 ( SMD inductance) as a trap for high frequency EMC trouble. Under normal circumstances you will not need it. And - unfortunatly - the 47pf cuts all the highest frequencies from your guitar signal like a bad guitar cable ! by the way....youÂ´ll never see such a capacitor e.g. in a high class tube guitar amps in the first stage. So, if there are no high frequencies from the strings .......the amplifier cannot amplify such details. And the sound will not be so bright, not so clear or crisp .....or what ever words you will use. But, if you like an open Tubeamp sound remove the C4 and you will be very happy with the improved sound. These mods should also work in HD147 Â´s , because they use the same technology inside as the Flextone III. A few words to the Line6 developers : I know the reasons well for building in the C4/L1 into the amps. Its because the CE and US trade specifications ! But for a musician it sounds much better without these absorption circuits. ;-) Thanks for this great Amp !!!!!! cheers Peter from Germany
