Topic: Sho-Bud Pro 1 mechanism differences? |

I noticed the blond Pro 1 for sale here on the forum. It's mechanism is different than the square front/narrow pedal Pro 1 that a friend of mine brought over yesterday for me to help him set up. The round front/wide pedal Pro 1 on the forum has the rods with the internal hex drive to adjust the changer tuning, and the square front I worked on had the nylon tuners at the end plate. The shafts and bell cranks look the same and the 'banjo fittings' on the bell cranks look similar. The square front had the rods held on the bell crank 'banjos' with allen set screws. Does the round front have threaded 'banjo fittings? Also does anyone know when the change to the mechanism occurred? Was it with the change to the square front?
Thanks, LarryRobertson

The change happened around late '74...if we're talking about the same thing.
The first gen Pro I's had what are called barrels - made of brass - at the bell cranks (called two-hole pullers in Bud jargon), and the tuning rods had a fixed hex cap at the changer.
The switch that occurred was to have the rods fixed at the pullers with a set screw and nylon tuners at the changer. Same principle, just happening at a different point in the mechanical setup.
Either one is fine... I prefer the barrel setup, and that seems to be the prevailing thought that alot of Bud players agree on... that barrels behind two hole pullers was Sho-Bud's golden era.
And, to answer your question, the switch to the square front body occured pretty much at the same time as the switch to nylon tuners. |

Hi guys, Skip, Thanks for the comments. Chris, by 'banjo fittings' I was referring to the round disk (I think it's brass) that the pull rod goes thru. That disk is secured to the bell crank and allows the rod to swivel on the bell crank. I guess using the term 'swivel fittng' might be more accurate. Skip, I am not sure how the barrel changes the effective length of the rod on that earlier mechanism. Is the barrel threaded? What actually happens when one turns the hex cap at the changer end? There's always more to learn on these steels. Thanks for the help. Larry

The rod doesn't swivel when it's attached with a set screw to the bell crank. The nylon tuners do the swiveling, since the rods are threaded at the end. With the fixed hex ends on the rods (at the changer), the rods swivel, since they're attached to the barrels with a set screw. The barrels (which are threaded)screw in and out, tuning the pull.
The barrel system is a marvel of simplicity, and extremely versatile, capable of unlimited pulls, since you can have as many barrels on a rod as you want...or at least as many as you have pedals & KL's for. |

Slight correction, Skip.
The barrels' length precludes having a raise on two adjacent shafts (if you have lever shafts between pedal shafts), so that provides some limitation. And requires some thought if you're gonna load up a universal, since some knees can't go next to some pedals.

Yeah Chris, I would like a sho-bud, but not sure which one! I'm getting too old to haul stuff anymore and that Pro 1 with 3&4 that my friend brought over sounded real sweet. But then, I sure do like the sound of my Emmons P/P so maybe a single P/P would suit me. You're correct though, I'm not gonna load up a bud. Thanks, Larry

| The later SuperPro mechanism is a superior design, allowing much more flexibility and clean, tight timing, but the pot-metal parts are prone to failure and they have gotten a bad rap as a result. Great guitars though... |

Dave, while it allows better pull timing¹, in terms of number of pulls², only push-pull and pull-release match (or in some cases, exceed) the two-hole Buds. The Excel comes close.
¹An overrated function, IMO. A lot of great music has come out of, and continues to come out of, notchy-playing guitars³.
²Also possibly overrated, but I value it.
³That said, I like my smooth-playing Zum
