Lakland 5501 vs 5501 Deluxe

Can anyone tell me what the Lakland 5501 deluxe has vs the regular 5501. I think they used a different preamp. My 2005 model has the soft knobs [splined shaft pots] which I understand is a different preamp. Just trying to understand if this is a significant upgrade from the factory. Thanks

 

Maybe I should have been more informative. I called Lakland because my metal knobs with set screw [OE] kept coming loose and need re-fitting [of course it took me 13 years of ownership to figure this out]. I called Leo at Lakland asking for a solution like the push on rubber knobs like on the 5502 [which I also own]. He said those only fit the 5501 deluxe, with spline shaft, which also has an upgraded preamp, not sure if that meant the USA preamp or ???. I should have asked him more questions about what that meant. Will do so later today and report back.

 

So I spoke with Lakland and they said if the 5501 [year 2005] has splined/split [not solid] shafts on the pots its the same preamp they put in the US 55-94

 

yep, if you have soft touch, push on knobs you might want to check your preamp out
