John Entwistle was the Who's legendary bass player, but was also very well known for his large bass guitar collection (you can check out many of his instruments in the highly recommended book Bass Culture: The John Entwistle Guitar Collection). So it may be unsurprising that UK music magazine Beat Instrumental persuaded him to take a look at the new Guild B-301 bass, as part of their usual monthly reviews of new gear, for the July 1977 issue.

As usual the instrument is given a good play, and a qualitative assessment made. Entwistle comes across as somewhat unimpressed, but perhaps this is not too surprising, as the single pickup passive B-301 is a long way from the active Alembic guitars that he was using in the late 1970s, but he does highlight its good build quality, something with which modern day Guild players/collectors would agree. His main complaint is the adjustability of the bridge, and is maybe a bit harsh; these were a vast improvement on the old Hagstrom bass bridges used previously. Other comments about the control knobs and the pickup mounting screws have not borne out: the pickup screws attach to a brass plate, and it's quite stable. The knobs have typically proven to be very durable over the last decades.
The article is reproduced below. Perhaps Beat Instrumental regretted such an unfavorable review, as their "policy of asking established and respected musicians to conduct instrument reviews" seems to have declined after this one!

Beat Instrumental, July 1977
Continuing our policy of asking established and respected musicians to conduct instrument reviews for us, we timorously set off to John Entwistle, armed with a new Guild B-301 bass. Fortunately for us, John agreed happily to the idea, but then immediately plugged the thing in and told us to get our notebooks out - which we did, for after all, he's the player and we're supposed to be the writers. (Pause for laughter... Ed.)
J.E: Forming opinions rapidly may not always be the best way of reviewing an instrument but when you've been playing for as long as I have, and have had the opportunity to play as many different guitars, you tend to know what to look for.
B.I: Such as?
J.E: Well, two main approaches. Firstly, what you can see, and secondly what you can hear and feel. Looking at an instrument can tell you as much about it as playing it. If it looks as if it's been well-thought out and well manufactured, at least you've got reason to suppose that it will play and sound all right. The shape of this one is pretty insignificant for example. The neck suffers from the same mistake that most so-called long neck guitars do - that is it goes from E to E flat. Why couldn't they have added one extra fret to give it a full scale? The control knobs too, they look revolting, as if they're going to shatter at any moment.
B.I: What about the bridge?
J.E: Well, it looks all right at first but (struggling to turn the screws) why have they given the bridge screws serrated edges when there's a screw slot on the top as well? Either it can be adjusted by hand or by screwdriver - and I can't even turn this one at all!
Another problem with the bridge appears to be the fact that there are no individual adjusters for each string - something which I happen to prefer?
B.I: (getting a little worried!) Is there nothing good to say about its appearance then?
J.E: Well, the heads look good, and the general overall feel of the instrument is reassuring as well. It looks well made _ apart from the criticisms I‘ve already made, and it obviously hasn't't been put together in a rush with a devil may care attitude.
B.I: Would you like to play it now?
John plugged the beast in and we sat back being treated to a private bass playing concert which had to be heard to be believed. The old cliché about being a fine bass player is too great an understatement, but it was exceptionally interesting to hear his technique out of context, so to speak.
J.E: Well, the pick-up sounds pretty good, and the action is excellent, allowing me to move quickly and cleanly around without any difficulty at all. The controls seem to give a very good variation in sound as well, and with a bit more time to work on different arrangements I think there could be some excellent differing tones available in there. On the other hand, my suspicions about the bridge have been confirmed.
B.I: In what way?
J.E: Well, like I said earlier, its looks don't exactly inspire confidence, and its construction when playing is quite appalling. The small screw at the front of the bridge should really be stuck up the designer's nose, and the two larger strings are stopping me from dampening the strings properly. And listen to this . . . (He thudded the G string) - that sounds more like a bass sitar as it's rattling against the bridge.
B.I: Anything else?
J.E: Well, while we're down this end of the guitar I think I ought to mention the pick-up. it's much too springy, These two small screws may well fall out after a time on stage with the Who for example - and that really could cause a problem or two.
B.I: What about your overall impression then?
J.E: Well, it must be understood that I'm very discerning about bass guitars in particular, and guitars in general, so I'm likely to criticise various aspects of its construction and sound which perhaps most other bass players, especially in the semi-pro field, wouldn't worry about. But being a perfectionist on matters like these is hardly a crime; I would temper my criticisms with the reminder that I am very particular... all right? But overall it's quite a good bass guitar; the sound is good, the tone easily variable, and the action and neck very good indeed, but it is a shame about the bridge, and I would seriously suggest that Guild rethink this part of the guitar. In relation to their other efforts it's not really any better than previous models except in the actual sound, but it is undoubtedly better than most of the American guitars on the market and does represent honest value for money. If only they re-designed the bridge...
B.I: Thanks very much John.
