A note regarding reviews: Product reviews on this site are the result of me buying the reviewed equipment off the shelf or online. In the event that a vendor has provided a free sample for review, that fact will be plainly stated in the review and the vendor will be informed that I will post my true feelings, whatever they may be. Come to think of it, that may be why I don’t get many free items from vendors to review.

  3. Hi Gary–

    I write a blog about pet insurance in Australia.

    We just did a price comparison of over 100 breeds, and Newfoundlands ranked as the most expensive breed to insure, costing over $3,000 per year!

    I don’t have much firsthand experience with Newfoundlands, and would like to add a couple quotes to the article from a Newfoundland expert on why rates may be so high, what owners can do to keep the costs of care reasonable, and if anyone actually pays such sky high premiums for their dog.

    I’d very much appreciate if you’re able to share a few thoughts for inclusion in our article.

    Thanks very much!


  4. Gary, I saw your video on the Rigexpert 230 zoom. I am considering an antenna analyzer and trying to decide between the 230 zoom and the AA-1000. I would appreciate your input. Thanks.

    1. It really depends on your needs. I never do anything above the 70cm band, so the added range is lost on me. If you need the higher range, then the choice is made.

  5. Gary:

    I have a mint condition Guild S300A-D I am considering selling. I bought it new about 40 years ago, and it has been sitting unplayed in my closet for decades (bass is my instrument). Please contact me if interested. Thanks.

      1. Hey Konrad – sorry I didn’t put this together sooner. I now own the guitar that Michael was talking about in his post.

  6. Gary,

    Great site !! Very interesting to me as a Guild Guitar lover. I have a 1964 Jetstar as well as a 2000 Bluesbird. I once bought an early ’50s, (’52 or ’53 I think), X-350 which was incredible but I sold it to a friend who really needed a good guitar at the time.
    I play guitar in The Barn Cats,
    & The Crackers,
    as well as having a long career of being a music photographer,
    Thanks very much for all the information you have shared in such a pleasant manner.

  7. Hi Garry,
    Great site !! I’m new into Guild electrics and I found a lot of information here. I got one acoustic DV-4 which is great guitar and that let me to think about buying some Guild solid body. I consider buying S-300 and found somewhere in your posts that your review of S300A-D is coming. Is t? I don’t know what wood to choose. So, do you have any sound samples of your S300 A-D to compare with those in your S300 review?
    That would be very helpful.


    1. Yes a review of the S300A-D is forthcoming. No I don’t know when. As a result, I do not yet have samples of the S300A-D to compare. That may soon change depending on my other workloads.

  8. I enjoy your site. I just got my first Starfire (I once had a wicked Dearmond SF Special and vowed to get the real deal) , a Blonde 2000 SFIII with the mushy Fender pickups. I knew that when I bought it. I have a trusted shop guy who will rewind them for me. Are there any specs I should request on the rewind ? Thanks

  9. Hi Gary

    I am new to Arista and am watching ACE -Essentials videos,Please can you tell me how to enlarge that video of you talking in the slides ?


  10. Hi GAD,
    Thanks for compiling all the information on Guild Pickups! I have a1997 Starfire iv (blonde) and I want to tame the high frequencies and to reduce the pickup output. I’m thinking of doing a magnet swap and inserting an A2 in the bridge and A3 in the neck; have you ever done any magnet swaps with these pickups and, if so, what did you think of the results?
